     The transistors in the reset control shift register unit  105  as shown in  FIG.  1 B  are all described by using P-type transistors as an example, that is, each transistor is turned on in the case where a gate electrode of the transistor is connected to a low level (turned-on level), and is turned off in the case where the gate electrode of the transistor is connected to a high level (turned-off level). In this case, the first electrode of the transistor can be a source electrode, and the second electrode of the transistor can be a drain electrode. 
     The reset control shift register unit includes, but is not limited to, the configuration as shown in  FIG.  1 B , for example, respective transistors in the reset control shift register unit  105  may also adopt N-type transistors or a combination of P-type transistors and N-type transistors, so long as the respective port polarities of the selected type transistor are connected according to the port polarities of the corresponding transistor in the embodiments of the present disclosure. 
     It should be noted that the transistors used in the reset control shift register unit can all be thin film transistors or field effect transistors or other switching devices with the same characteristics. Here, thin film transistors are used as examples for description. For example, an active layer (channel region) of the transistor is made of semiconductor materials, such as polysilicon (such as low-temperature polysilicon or high-temperature polysilicon), amorphous silicon, indium gallium tin oxide (IGZO), etc., while a gate electrode, a source electrode, a drain electrode, etc. of the transistor are made of metal materials, such as metal aluminum or aluminum alloy. The source electrode and the drain electrode of the transistor used here can be symmetrical in structure, and therefore, the source electrode and the drain electrode of the transistor can have no difference in structure. In the embodiments of the present disclosure, in order to distinguish the two electrodes of the transistor other than the gate electrode, one electrode of the two electrodes is directly described as a first electrode and the other electrode of the two electrodes is described as a second electrode. In addition, in the embodiments of the present disclosure, the electrodes of the capacitor may be metal electrodes or one of the electrodes of the capacitor may be made of a semiconductor material (for example, doped polysilicon). 
       FIG.  1 C  is a signal timing diagram of the reset control shift register unit  105  shown in  FIG.  1 B  during operation. The working process of the reset control shift register unit will be described in detail below in conjunction with  FIG.  1 B  and  FIG.  1 C . For example, the working principle of the first stage of reset control shift register unit  105  will be described, and the working principles of the reset control shift register units  105  in the other stages are similar to this case, and will not be repeated. As shown in  FIG.  1 C , the working process of the reset control shift register unit  105  includes 6 phases, namely a first phase t1, a second phase t2, a third phase t3, a fourth phase t4, a fifth phase t5, and a sixth phase t6, and  FIG.  1 C  shows the timing waveforms of the various signals in each phase. 
     In the input phase t1, as shown in  FIG.  1 C , the first clock signal line provides a high level, and therefore, the first clock signal terminal CK connected to the first clock signal line receives the high-level first clock signal, and the input transistor T 6  is turned off. Due to the storage effect of the first capacitor C 1 , the level of the third node N 3  can be maintained at a high level, so that the output transistor T 7  is turned off. The fifth control transistor T 5  is turned on in response to the low-level second voltage, so that the level of the fourth node N 4  becomes a high level, and the fourth control transistor T 4  is turned off. The trigger signal line provides a low level. Therefore, the input terminal EI connected to the trigger signal line receives a low-level trigger signal, and the first control transistor T 1  is turned on. The second clock signal line provides a low level. Therefore, the second clock signal terminal CB connected to the second clock signal line receives a low-level second clock signal, and the second control transistor T 2  is turned on. The high-level first voltage is transmitted to the first node N 1  through the turned-on first control transistor T 1  and the turned-on second control transistor T 2 , so that the level of the first node N 1  becomes a high level, and the third control transistor T 3  is turned off. Due to the storage effect of the second capacitor C 2 , the level of the second node N 2  can be maintained at a low level, so that the output control transistor T 8  is turned on. The high-level first voltage is transmitted to the output terminal EOUT through the turned-on output control transistor T 8 . Therefore, in the first phase P 1 , the output signal output by the output terminal EOUT of the reset control shift register unit  105  is at a high level. 
     In the second phase P 2 , as shown in  FIG.  1 C , the input terminal EI receives the low-level trigger signal provided by the trigger signal line, and the first control transistor T 1  is turned on. The second clock signal terminal CB receives the high-level second clock signal provided by the second clock signal line, and the second control transistor T 2  is turned off. The high-level first voltage is transmitted to the first node N 1  through the turned-on first control transistor T 1 , so that the level of the first node N 1  becomes a high level, and the third control transistor T 3  is turned off. The first clock signal terminal CK receives the low-level first clock signal provided by the first clock signal line, and the input transistor T 6  is turned on. Because the input terminal EI receives the low-level trigger signal provided by the trigger signal line, the level of the fourth node N 4  becomes a low level, so that the fourth control transistor T 4  is turned on. The high-level first voltage is transmitted to the second node N 2  through the turned-on fourth control transistor T 4 , so that the output control transistor T 8  is turned off. The fifth control transistor T 5  is turned on in response to the low-level second voltage, so that the level of the third node N 3  becomes a low level, therefore, the output transistor T 7  is turned on, and the low-level second voltage is transmitted to the output terminal EOUT through the turned-on output transistor T 7 . Therefore, in the second phase P 2 , the output signal output by the output terminal EOUT of the reset control shift register unit  105  is at a low level. 
     In the third phase P 3 , as shown in  FIG.  1 C , the input terminal EI receives the low-level trigger signal provided by the trigger signal line, and the first control transistor T 1  is turned on. The second clock signal terminal CB receives the low-level second clock signal provided by the second clock signal line, and the second control transistor T 2  is turned on. The high-level first voltage is transmitted to the first node N 1  through the turned-on first control transistor T 1  and the turned-on second control transistor T 2 , so that the level of the first node N 1  becomes a high level, and the third control transistor T 3  is turned off. Due to the storage effect of the second capacitor C 2 , the level of the second node N 2  can be maintained at a high level, so that the output control transistor T 8  is turned off. The first clock signal terminal CK receives the high-level first clock signal provided by the first clock signal line, and the input transistor T 6  is turned off. Due to the storage effect of the first capacitor C 1 , the level of the third node N 3  can be maintained at a low level, so that the output transistor T 7  is turned on, the low-level second voltage is transmitted to the output terminal EOUT through the turned-on output transistor T 7 . At the same time, the level of the third node N 3  is further pulled down to be lower than the second voltage, so that the fifth control transistor T 5  is turned off. Therefore, in the third phase P 3 , the output signal output by the output terminal EOUT of the reset control shift register unit  105  is at a low level. 
     In the fourth phase P 4 , as shown in  FIG.  1 C , the input terminal EI receives the low-level trigger signal provided by the trigger signal line, and the first control transistor T 1  is turned on. The second clock signal terminal CB receives the high-level second clock signal provided by the second clock signal line, and the second control transistor T 2  is turned off. The high-level first voltage is transmitted to the first node N 1  through the turned-on first control transistor T 1 , so that the level of the first node N 1  becomes a high level, and the third control transistor T 3  is turned off. The first clock signal terminal CK receives the low-level first clock signal provided by the first clock signal line, and the input transistor T 6  is turned on. Because the input terminal EI receives the low-level trigger signal provided by the trigger signal line, the level of the fourth node N 4  becomes a low level, so that the fourth control transistor T 4  is turned on. The high-level first voltage is transmitted to the second node N 2  through the turned-on fourth control transistor T 4 , so that the output control transistor T 8  is turned off. Due to the storage effect of the first capacitor C 1 , the level of the third node N 3  can be maintained at a low level, so that the output transistor T 7  is turned on, and the low-level second voltage is transmitted to the output terminal EOUT through the turned-on output transistor T 7 . At the same time, the level of the third node N 3  is further pulled down to be lower than the second voltage, so that the fifth control transistor T 5  is turned off. Therefore, in the fourth phase P 4 , the output signal output by the output terminal EOUT of the reset control shift register unit  105  is at a low level. 
     In the fifth phase P 5 , as shown in  FIG.  1 C , the input terminal EI receives the high-level trigger signal provided by the trigger signal line, and the first control transistor T 1  is turned off. The second clock signal terminal CB receives the low-level second clock signal provided by the second clock signal line, and the second control transistor T 2  is turned on. The high-level first voltage is transmitted to the first node N 1  through the turned-on second control transistor T 2 , so that the level of the first node N 1  becomes a high level, and the third control transistor T 3  is turned off. Due to the storage effect of the second capacitor C 2 , the level of the second node N 2  can be maintained at a high level, so that the output control transistor T 8  is turned off. The first clock signal terminal CK receives the high-level first clock signal provided by the first clock signal line, and the input transistor T 6  is turned off. Due to the storage effect of the first capacitor C 1 , the level of the third node N 3  can be maintained at a low level, so that the output transistor T 7  is turned on, and the low-level second voltage is transmitted to the output terminal EOUT through the turned-on output transistor T 7 . At the same time, the level of the third node N 3  is further pulled down to be lower than the second voltage, so that the fifth control transistor T 5  is turned off. Therefore, in the fifth phase P 5 , the output signal output by the output terminal EOUT of the reset control shift register unit  105  is at a low level. 
     In the sixth phase P 6 , as shown in  FIG.  1 C , the first clock signal terminal CK receives the low-level first clock signal provided by the first clock signal line, and the input transistor T 6  is turned on. Because the input terminal EI receives the high-level trigger signal provided by the trigger signal line, the level of the fourth node N 4  becomes a high level, so that the fourth control transistor T 4  is turned off. The fifth control transistor T 5  is turned on in response to the low-level second voltage, so that the level of the third node N 3  becomes a high level, and therefore, the output transistor T 7  is turned off. The input terminal EI receives the high-level trigger signal provided by the trigger signal line, and the first control transistor T 1  is turned off. The second clock signal terminal CB receives the high-level second clock signal provided by the second clock signal line, and the second control transistor T 2  is turned off. Due to the storage effect of the third capacitor C 3 , under the action of the low-level first clock signal received by the first clock signal terminal CK, the level of the first node N 1  becomes a low level, so that the third control transistor T 3  is turned on. The low level received by the first clock signal terminal CK is transmitted to the second node N 2  through the turned-on third control transistor T 3 , so that the output control transistor T 8  is turned on. The high-level first voltage is transmitted to the output terminal EOUT through the turned-on output control transistor T 8 . Therefore, in the sixth phase P 6 , the output signal output by the output terminal EOUT of the reset control shift register unit  105  is at a high level. 
     As AMOLED (Active-matrix organic light-emitting diode) technology matures, more and more mobile terminals use the AMOLED as a display panel. At present, for market, an AMOLED product with a narrow frame has more competitive advantages and are favored by more consumers. However, the size of the frame is not only affected by the encapsulation technology, but also is largely limited by the overall size of the GOA (for example, the gate drive circuit, the reset control drive circuit array, and the light-emitting control drive circuit array, etc.). The larger the size of the GOA, the larger the sizes of the left frame and the right frame of the panel, conversely, the smaller the size of the GOA, the narrower the frame. However, at present, by taking the reset control drive circuit array as an example, the arrangement of transistors and capacitors in GOA occupies a large space in a direction from the left frame to the right frame of the panel, which causes a waste of layout space of the display substrate and is not conducive to the implementation of the narrow frame of the display substrate.

     At least one embodiment of the present disclosure also provides a display device corresponding to the above-mentioned display substrate and a manufacturing method of the display substrate. 
     The display substrate provided by the above-mentioned embodiments of the present disclosure optimizes the circuit connection and structure layout of the shift register unit, compresses the size of the shift register unit in the second direction to a certain extent, reduces the space that the shift register unit needs to occupy in the peripheral region of the display substrate, which facilitates the implementation of the narrow frame design of the display substrate, and at the same time ensures the display quality of the display substrate. 
     Hereinafter, embodiments of the present disclosure will be explained in detail with reference to the drawings. It should be noted that the same reference numeral in different drawings will be used to refer to the same element that has been described. 
       FIG.  2 A  is a schematic diagram of a layout of a display substrate provided by at least one embodiment of the present disclosure. 
     For example, as shown in  FIG.  2 A , the display substrate includes a base substrate  10 , and a shift register unit  105 , a first power line VGH, a second power line VGL, and a plurality of clock signal lines, which are disposed on the base substrate  10 , for example, the plurality of clock signal lines may include the first clock signal line ECK, the second clock signal line ECB, and the trigger signal line ESTV shown in  FIG.  2 A . For example, in an embodiment of the present disclosure, the shift register unit  105  may be the reset control shift register unit  105  as shown in  FIG.  1 B . For the sake of convenience and conciseness, hereinafter, the reset control shift register unit  105  will be referred to as a shift register unit for short to describe the present disclosure. 
     For example, the first power line VGH, the second power line VGL, and the plurality of clock signal lines (for example, the first clock signal line ECK, the second clock signal line ECB, and the trigger signal line ESTV) extend along the first direction Y on the base substrate  10 , and are configured to respectively provide a first voltage, a second voltage, and a plurality of clock signals (for example, a first clock signal, a second clock signal, or a trigger signal, etc.) to the shift register unit  105 . For example, the first power line VGH is configured to provide the first voltage to the shift register unit  105 , the second power line VGL is configured to provide the second voltage to the shift register unit  105 ; the first clock signal line ECK and the second clock signal line ECB are configured to provide the first clock signal or the second clock signal to the shift register unit  105 , respectively. For example, the second voltage is less than the first voltage, for example, the first voltage is a high DC level, and the second voltage is a low DC level. For the specific connection relationship between the first power line VGH, the second power line VGL, as well as the plurality of clock signal lines, and the shift register unit  105 , can refer to the following description. 
     It should be noted that in the embodiments of the present disclosure, the case that the first clock signal line ECK is used to provide the first clock signal to the shift register unit  105  and the second clock signal line ECB is used to provide the second clock signal to the shift register unit  105  is taken as an example to illustrate, the embodiments of the present disclosure include but are not limited to this case; in some other embodiments of the present disclosure, it may also be that the first clock signal line ECK provides the second clock signal to the shift register unit  105 , and the second clock signal line ECB provides the first clock signal to the shift register unit  105 , and the embodiments of the present disclosure are not limited to this case. 
     It should be noted that the first power line VGH, the second power line VGL, and the plurality of clock signal lines may extend along the first direction Y and be arranged parallel to each other, or may also cross a certain angle (for example, less than or equal to 20°), and the embodiments of the present disclosure are not limited to this case. 
     For example, the base substrate  10  can be made of, for example, glass, plastic, quartz, or other suitable materials, and the embodiments of the present disclosure are not limited to this case. 
     For example, referring to  FIGS.  1 A and  2 A , the display substrate provided by the embodiments of the present disclosure includes a display region  102  (for example, the display region  102  may also be referred to as a pixel array region) and a peripheral region  106  located on at least one side of the pixel array region. For example, the above-mentioned first power line VGH, the above-mentioned second power line VGL, the above-mentioned plurality of clock signal lines, and the above-mentioned shift register unit  105  are located on the peripheral region  106  of the base substrate  10  and on a side of the base substrate  10  (as shown in  FIG.  1 A , located between the display region  102  and a side edge of the base substrate  10 ), for example, as shown in  FIG.  1 A , can be located on the left side and the right side of the base substrate  10 , of course, can also be located on the left side or the right side of the base substrate  10 , and the embodiments of the present disclosure are not limited to this case. 
     For example, an orthographic projection of the second power line VGL on the base substrate  10  and orthographic projections of the plurality of clock signal lines on the base substrate  10  are all located on a side of an orthographic projection of the shift register unit  105  on the base substrate  10  away from the display region  102 , for example, in the second direction X, are all located on the left side of the shift register unit  105  shown in  FIG.  2 A . An orthographic projection of the first power line VGH on the base substrate  10  partially overlaps with the orthographic projection of the shift register unit  105  on the base substrate  10 , and is located on a side of the orthographic projection of the shift register unit  105  on the base substrate  10  close to the display region  102 , for example, in the second direction X, the first power line VGH is located on the right side of the shift register unit  105  as shown in  FIG.  2 A , that is, is located between the orthographic projection of the shift register unit  105  on the base substrate  10  and the display region  102 . That is, the orthographic projection of the shift register unit  105  on the base substrate  10  is located between the orthographic projection of the first power line VGH on the base substrate  10  and the orthographic projection of the second power line VGL on the base substrate  10 . 
     For example, as shown in  FIG.  2 A , the orthographic projection of the second power line VGL on the base substrate  10  is located between the orthographic projections of the first clock signal line ECK as well as the second clock signal line ECB on the base substrate  10  and the orthographic projection of the shift register unit  105  on the base substrate  10 . For example, the first clock signal line ECK and the second clock signal line ECB are sequentially arranged from right to left along the second direction X on the base substrate  10 , that is, the orthographic projection of the second clock signal line ECB on the base substrate  10  is located on a side of the orthographic projection of the first clock signal line ECK on the base substrate  10  away from the orthographic projection of the second power line VGL on the base substrate  10 . 
     It should be noted that the above-mentioned plurality of clock signal lines may also include a trigger signal line ESTV that provides a trigger signal. For example, an orthographic projection of the trigger signal line ESTV on the base substrate  10  may be located on a side of the orthographic projections of the first clock signal line ECK and the second clock signal line ECB on the base substrate  10  away from the orthographic projection of the shift register unit  105  on the base substrate  10 , that is, the first clock signal line ECK, the second clock signal line ECB, and the trigger signal line ESTV are sequentially arranged from right to left along the second direction X on the base substrate  10 . 
     It should be noted that the above wiring positions are only exemplary, as long as it can be satisfied that the settings of the lines facilitate the connection between the lines and the shift register unit, and the embodiments of the present disclosure are not limited to this case. 
     For example, the included angle between the first direction Y and the second direction X is between 70° and 90°, and includes 70° and 90°. For example, the included angle between the first direction Y and the second direction X can be 70°, 75°, 80°, 85°, or 90°, etc.. The specific value of the included angle can be set according to actual conditions, and is not limited in the embodiments of the present disclosure. 
     For example, the display region  102  includes a plurality of pixel units  103  arranged in an array. For example, each of the plurality of pixel units  103  includes a pixel circuit, for example, may further include a light-emitting element (not shown in the figure). 
     For example, a plurality of shift register units  105  (that is, the reset control shift register units  105 ) that are cascaded constitute a reset control drive circuit array. For example, the output terminals EOUT of the plurality of shift register units  105  are respectively connected to the reset control signal terminals of respective rows of pixel circuits located in the pixel array region to provide output signals (for example, the reset control signals) to the respective rows of pixel circuits, thereby achieving driving the light-emitting element to emit light. For example, the pixel circuit may be a pixel circuit including circuit structures, such as 7T1C, 2T1C, 4T2C, 8T2C, etc. in the art, which will not be repeated here. 
     It should be noted that  FIG.  2 A  shows only a K-th (K is an odd number greater than 1) stage of shift register unit  105  in the gate drive circuit. For example, a first clock signal terminal CK of a first stage of shift register unit (not shown in the figure) is connected to the first clock signal line ECK to receive the first clock signal, a second clock signal terminal CB of the first stage of shift register unit is connected to the second clock signal line ECB to receive the second clock signal, a first clock signal terminal CK of a second stage of shift register unit (not shown in the figure) is connected to the second clock signal line ECB to receive the first clock signal, a second clock signal terminal CB of the second stage of shift register unit is connected to the first clock signal line ECK to receive the second clock signal, and so on. For example, as shown in  FIG.  2 A , a first clock signal terminal CK of the K-th (K is an odd number greater than 1) stage of shift register unit  105  is connected to the first clock signal line ECK to receive the first clock signal, a second clock signal terminal CB of the K-th stage of shift register unit  105  is connected to the second clock signal line ECB to receive the second clock signal, a first clock signal terminal CK of a (K+1)-th stage of shift register unit is connected to the second clock signal line ECB to receive the first clock signal, and a second clock signal terminal CB of the (K+1)-th stage of shift register unit is connected to the first clock signal line ECK to receive the second clock signal. It should be noted that, the connection mode between each stage of the shift register units and the clock signal lines may also adopt other connection modes in the art, and is not limited in the embodiments of the present disclosure. For example, an input terminal EI of the first stage of shift register unit is connected to the trigger signal line ESTV to receive the trigger signal as an input signal, an input terminal of the second stage of shift register unit is connected to an output terminal EOUT of a previous stage of shift register unit (for example, the first stage of shift register unit). The connection mode of the shift register units in other stages is similar to this case. The following takes the structure of the K-th stage of shift register unit  105  as an example for description, and the embodiments of the present disclosure are not limited in this aspect.

Correspondingly, in the case where the number of clock signal lines changes, the connection relationship between the shift register unit  105  and the clock signal lines in the display substrate also changes accordingly. The specific content can refer to conventional designs in the field, and will not be repeated here.

FIG.  8    is a cross-sectional view of some examples of the display substrate shown in  FIG.  2 A  along an A-A′ direction. For example, the A-A′ direction can be understood as: a direction along a first electrode SD 11  of the first control transistor T 1  → a second electrode SD 12  of the first control transistor T 1  → a second electrode SD 22  of the second control transistor T 2  → a first electrode SD 21  of the second control transistor T 2 , or a direction along the first electrode SD 21  of the second control transistor T 2  → the second electrode SD 22  of the second control transistor T 2  → the second electrode SD 12  of the first control transistor T 1  → the first electrode SD 11  of the first control transistor T 1 . For example, the cross-sectional view as shown in  FIG.  8    may correspond to the structure of the first control transistor T 1  and the second control transistor T 2 . The laminated structure of the display substrate provided by at least one embodiment of the present disclosure will be described in detail below with reference to  FIG.  2 A -8. 
     For example, an interlayer insulating layer (for example, including a first insulating layer, a second insulating layer, a third insulating layer, etc.) of the display substrate may be located between the layer structures as shown in  FIG.  3 A  to 7. For example, the first insulating layer  350  (as shown in  FIG.  8   ) is located between the semiconductor layer  310  as shown in  FIG.  3 A  and the first conductive layer  320  as shown in  FIG.  4   , the second insulating layer  360  (as shown in  FIG.  8   ) is located between the first conductive layer  320  as shown in  FIG.  4    and the second conductive layer  330  as shown in  FIG.  5   , and the third insulating layer  370  (as shown in  FIG.  8   ) is located between the second conductive layer  330  as shown in  FIG.  5    and the third conductive layer  340  as shown in  FIG.  7   . The holes as shown in  FIG.  6    are holes that penetrate one or more layers selected from a group consisting of the first insulating layer  350 , the second insulating layer  360 , and the third insulating layer  370 . 
     For example, as shown in  FIG.  8   , the display substrate further includes a fourth insulating layer  380 , and the fourth insulating layer  380  is located on the third conductive layer  340 , that is, on the side of the third conductive layer  340  away from the base substrate  10 , so as to protect the third conductive layer  340 . 
     For example, the materials of the first insulating layer  350 , the second insulating layer  360 , the third insulating layer  370 , and the fourth insulating layer  380  may include inorganic insulating materials, such as SiNx, SiOx, SiNxOy, and organic insulating materials, such as organic resins, or other suitable materials, and are not limited in the embodiments of the present disclosure. 
     It should be noted that the display substrate as shown in  FIG.  2 A  is described by taking the case that the layout design of the K-th stage of shift register unit in the reset control drive circuit array and the first power line, the second power line, and the clock signal lines connected to the K-th stage of shift register unit as an example, the layout implementation modes of the remaining shift register units in various stages can refer to the layout mode as shown in  FIG.  2 A , and will not be repeated here. Of course, other suitable layout modes may also be adopted, and the embodiments of the present disclosure are not limited to this case. Of course, the shift register units in various stages in the other reset control drive circuit array can also refer to the layout mode as shown in  FIG.  2 A , and or other suitable layout implementations can also be adopted, and the embodiments of the present disclosure are not limited to this case. 
     The display substrate provided by at least one embodiment of the present disclosure will be described in detail below with reference to  FIG.  2 A -8. 
     For example, the active layers A 1 ~A 8  of the first control transistor T 1 , the second control transistor T 2 , the third control transistor T 3 , the fourth control transistor T 4 , the fifth control transistor T 5 , the input transistor T 6 , the output transistor T 7 , and the output control transistor T 8  of the shift register unit  105  as shown in  FIG.  2 A  may be formed on the semiconductor layer  310  as shown in  FIG.  3 A . The semiconductor layer  310  may be formed by patterning a semiconductor material. For example, as shown in  FIG.  3 A , according to actual different requirements, the semiconductor layer  310  can comprise a short rod-shape portion or a portion having a curved or bent shape, so as to form the active layers A 1 ~A 8  of the above-mentioned transistors T 1  to T 8 . The active layer of each transistor may include a source region, a drain region, and a channel region between the source region and the drain region. For example, the channel region has semiconductor characteristics; the source region and the drain region are on both sides of the channel region, respectively, and can be doped with impurities and therefore have conductivity. For example, the source region is a portion of the active layer, and a metal electrode (for example, located in the third conductive layer  340 ) in contact with the source region corresponds to the source electrode (or called the first electrode) of the transistor; the drain region is a portion of the active layer, and a metal electrode (for example, located in the third conductive layer  340 ) in contact with the drain region corresponds to the drain electrode (or called the second electrode) of the transistor. For example, the source region is connected to a metal electrode (source electrode) corresponding thereto through a hole penetrating the first insulation layer  350 , the second insulation layer  360 , and the third insulation layer  370 , and the drain region is connected to a metal electrode (drain electrode) corresponding thereto through a hole penetrating the first insulation layer  350 , the second insulation layer  360 , and the third insulation layer  370 . 
     For example, by taking the first control transistor T 1  and the second control transistor T 2  as an example, as shown in  FIG.  8   , the first electrode SD 11  of the first control transistor T 1  is connected to the source region of the active layer A 1  of the first control transistor T 1  through a hole H 1  penetrating the third insulating layer  370 , the second insulating layer  360 , and the first insulating layer  350 , and the second electrode SD 12  of the first control transistor T 1  is connected to the drain region of the active layer A 1  of the first control transistor T 1  through a hole H 2  penetrating the third insulating layer  370 , the second insulating layer  360 , and the first insulating layer  350 ; the second electrode SD 22  of the second control transistor T 2  is connected to the drain region of the active layer A 2  of the second control transistor T 2  through a hole H 3  penetrating the third insulating layer  370 , the second insulating layer  360 , and the first insulating layer  350 , and the first electrode SD 21  of the second control transistor T 2  is connected to the source region of the active layer A 2  of the second control transistor T 2  through a hole H 4  penetrating the third insulating layer  370 , the second insulating layer  360 , and the first insulating layer  350 . 
     For example, the material of the semiconductor layer  310  may include oxide semiconductors, organic semiconductors, or amorphous silicon, polysilicon, etc., for example, the oxide semiconductors include metal oxide semiconductors (such as indium gallium zinc oxide (IGZO)), and the polysilicon includes low-temperature polysilicon, high-temperature polysilicon, or the like, and the embodiments of the present disclosure are not limited to this case. It should be noted that the above-mentioned source region and drain region may be regions doped with n-type impurities or p-type impurities, and the embodiments of the present disclosure are not limited to this case. 
     It should be noted that in other examples, the first electrode and the second electrode of each transistor can also be located in other conductive layers, and are connected to their corresponding active layers through holes in an insulating layer between the conductive layer and the semiconductor layer. The embodiments of the present disclosure are not limited to this case. 
       FIG.  4    shows the first conductive layer  320  of the display substrate. The first conductive layer  320  is disposed on the first insulating layer  350  so as to be insulated from the semiconductor layer  310 . For example, the first conductive layer  320  may include the first electrodes CE 11 , CE 12 , and CE 13  of the first capacitor C 1  to the third capacitor C 3 , and the gate electrodes G 1 ~G 8  of the transistors T 1 ~T 8  and various wires directly connected to the gate electrodes G 1 ~G 8  (for example, a first connection wire L 1 , a second connection wire L 2 , the third connection wire L 3 , and the fourth connection wire L 4 ), and correspondingly, the first insulating layer  350  can also serve as a gate insulating layer. As shown in  FIG.  4   , the gate electrodes G 1 ~G 8  of the transistors T 1 ~T 8  are the portions enclosed by circular or elliptical dashed circles, that is, the portions where the semiconductor layer structures of respective transistors overlap with the electrodes or wires on the first conductive layer  320 . 
       FIG.  5    shows the second conductive layer  330  of the display substrate, the second conductive layer  330  includes the second electrodes CE 21 , CE 22 , CE 23  of the first capacitor C 1  to the third capacitor C 3 , and wires (for example, an electrode connection wire M 1 ) for connecting with signal lines or transfer electrodes on the third conductive layer  340 . For example, the second electrode CE 21  and the first electrode CE 11  at least partially overlap to form the first capacitor C 1 , the second electrode CE 22  and the first electrode CE 12  at least partially overlap to form the second capacitor C 2 , and the second electrode CE 23  and the first electrode CE 13  at least partially overlap to form the third capacitor C 3 . 
       FIG.  7    shows the third conductive layer  340  of the display substrate. The third conductive layer  340  includes a plurality of signal lines (for example, the first clock signal line ECK, the second clock signal line ECB, and the trigger signal line ESTV), the first power line VGH, and the second power line VGL, and the like. It should be noted that the third conductive layer  340  also includes a first transfer electrode  110 , a second transfer electrode  120 , a third transfer electrode  130 , a fourth transfer electrode  140 , a fifth transfer electrode  150 , a sixth transfer electrode  160 , a seventh transfer electrode  170 , a first power line transfer electrode  180 , a second power line transfer electrode  190 , and so on, which are connected among the transistors, the capacitors, and the signal lines. For example, the second transfer electrode  120  includes an input terminal EI, and the third transfer electrode  130  includes an output terminal EOUT. 
     It should be noted that, in the embodiments of the present disclosure, the second transfer electrode  120  located on the third conductive layer  340  may be used to receive an input signal; while in some other embodiments of the present disclosure, the input signal of the input terminal EI of the shift register unit  105  may also be received by electrodes located in other layers, that is, the input terminal EI may also be disposed in another layer different from the third conductive layer  340 , for example, may be disposed in the first conductive layer  320  or the second conductive layer  330 , which is not limited in the embodiment of the present disclosure. 
     It should be noted that, in the embodiments of the present disclosure, the third transfer electrode  130  located on the third conductive layer  340  may be used to provide an output signal; while in some other embodiments of the present disclosure, the output signal of the output terminal EOUT may also be provided by electrodes located in other layers, that is, the output terminal EOUT may also be disposed in another layer different from the third conductive layer  340 , for example, may be disposed in the first conductive layer  320  or the second conductive layer  330 , which is not limited in the embodiment of the present disclosure. 
     It should be noted that, in the embodiments of the present disclosure, the second transfer electrode  120  and the third transfer electrode  130  are both located in the third conductive layer  340 , therefore, in addition to the last stage of shift register unit  105 , the third transfer electrode  130  for providing an output signal can be connected to and be formed integrally with the second transfer electrode  120  in the next stage of shift register unit  105 , thereby providing the input signal to the input terminal EI of the next stage of shift register unit  105 ; in addition to the first stage of shift register unit  105 , the second transfer electrode  120  for receiving the input signal can be connected to and be formed integrally with the third transfer electrode  130  in the previous stage of shift register unit  105 , so as to receive the output signal of the output terminal EOUT of the previous stage of shift register unit  105  as the input signal of the input terminal EI of the current stage of shift register unit  105 . 
     As shown in  FIG.  2 A  to 7, the plurality of signal lines, the first power line VGH, and the second power line VGL are connected to the transistors and capacitors in the remaining layers that need to be connected to the plurality of signal lines, the first power line VGH, and the second power line VGL through at least one hole as shown in  FIG.  6   , and the respective transistors and the respective capacitors are also connected through at least one hole or are bridged through transfer electrodes, which will not be repeated here. 
     For example, the material of the third conductive layer  340  may include titanium, titanium alloy, aluminum, aluminum alloy, copper, copper alloy, or any other suitable composite materials, and the embodiments of the present disclosure are not limited to this case. For example, the material of the first conductive layer  320  and the material of the second conductive layer  330  may be the same as the material of the third conductive layer  340 , and similar portions will not be repeated here. 
       FIG.  2 A  is a schematic diagram of the stacking position relationship of the semiconductor layer  310  as shown in  FIG.  3 A , the first conductive layer  320  as shown in  FIG.  4   , the second conductive layer  330  as shown in  FIG.  5   , and the third conductive layer  340  as shown in  FIG.  7   . The display substrate provided by at least one embodiment of the present disclosure will be described in detail below with reference to  FIG.  2 A -8. 
     For example, as shown in  FIGS.  2 A and  3 A , the active layer A 1  of the first control transistor T 1  and the active layer A 2  of the second control transistor T 2  extend along a second direction X different from the first direction Y, respectively. An orthographic projection of the active layer A 1  of the first control transistor T 1  on the base substrate  10  and an orthographic projection of the active layer A 2  of the second control transistor T 2  on the base substrate  10  are located on a side of orthographic projections of the first clock signal line ECK and the second clock signal line ECB on the base substrate  10  close to the display region  102 , that is, in the second direction X, the active layer A 1  of the first control transistor T 1  and the active layer A 2  of the second control transistor T 2  are located on the right side of the first clock signal line ECK and the second clock signal line ECB. 
     For example, in conjunction with  FIG.  2 A ,  FIG.  2 B , and  FIG.  3 A , a minimum distance in the second direction X between the orthographic projection of the active layer A 1  of the first control transistor T 1  on the base substrate  10  and the orthographic projections of the first clock signal line ECK and the second clock signal line ECB on the base substrate  10  is a first distance D1, and a minimum distance in the second direction X between the orthographic projection of the active layer A 2  of the second control transistor T 2  on the base substrate  10  and the orthographic projections of the first clock signal line ECK and the second clock signal line ECB on the base substrate  10  is a second distance. For example, the first distance D1 is a spacing distance in the second direction X between the orthographic projection of the active layer A 1  of the first control transistor T 1  on the base substrate  10  and an edge of the side of the first clock signal line ECK close to the display region  102 , and the second distance D2 is a spacing distance in the second direction X between the orthographic projection of the active layer A 2  of the second control transistor T 2  on the base substrate  10  and an edge of the side of the first clock signal line ECK close to the display region  102 . A difference between the first distance D1 and the second distance D2 is greater than or equal to 0 and less than or equal to a size AL1 of the active layer A 1  of the first control transistor T 1  in the second direction X or a size AL2 of the active layer A 2  of the second control transistor T 2  in the second direction X, that is, 0≤ | D1-D2 | ≤AL1 or 0≤ | D1-D2 | ≤AL2. For example, AL1 is a length of the active layer A 1  of the first control transistor T 1  in the second direction X, and AL2 is a length of the active layer A 2  of the second control transistor T 2  in the second direction X. Thus, the active layer A 1  of the first control transistor T 1  and the active layer A 2  of the second control transistor T 2  are arranged side by side in the first direction Y. 
     Thus, by enabling the difference between the first distance D1 and the second distance D2 to be greater than or equal to 0 and less than or equal to the size AL1 of the active layer A 1  of the first control transistor T 1  in the second direction X or the size AL2 of the active layer A 2  of the second control transistor T 2  in the second direction X, the active layer A 1  of the first control transistor T 1  and the active layer A 2  of the second control transistor T 2  can be arranged side by side in the first direction Y, thereby reducing the size of the first control transistor T 1  and the size of the second control transistor T 2  in the second direction X, and optimizing the layout design of the first control transistor T 1  and the second control transistor T 2  in the shift register unit  105 . Furthermore, the size of the shift register unit  105  in the second direction X is reduced to a certain extent, and the space required by the shift register unit  105  in the peripheral region  106  of the display substrate is reduced, which is beneficial to achieve the narrow frame design of the display substrate and at the same time ensures the display quality of the display substrate. In addition, more sufficient space can be reserved for other transistors, capacitors, wires, etc. in the shift register unit  105 , so that the wiring connection and the structural layout of the shift register unit  105  can be further optimized. 
     For example, a range of the first distance D1 may be 30 µm to 60 µm, for example, 40 µm to 55 µm; a range of the second distance D2 may be 30 µm to 60 µm, for example, 40 µm to 55 µm. As a result, the layout settings of the first control transistor T 1  and the second control transistor T 2  in the first direction Y and the second direction X are further optimized. 
     For example, the first distance D1 may be 40 µm, 42 µm, 44 µm, 45 µm, 47 µm, 49 µm, 50 µm, 52 µm, 55 µm, etc., and the second distance D2 may be 40 µm, 42 µm, 44 µm, 45 µm, 47 µm, 49 µm, 50 µm, 52 µm, 55 µm, or the like. 
     For example, the size AL1 of the active layer A 1  of the first control transistor T 1  in the second direction X may be set to be similar to the size AL2 of the active layer A 2  of the second control transistor T 2  in the second direction X, thereby further optimizing the layout structure of the first control transistor T 1  and the second control transistor T 2  in the display substrate. 
     For example, as shown in  FIGS.  2 A and  4   , the gate electrode G 1  of the first control transistor T 1  and the gate electrode G 2  of the second control transistor T 2  are parallel to each other in the first direction Y, that is, the gate electrode G 1  of the first control transistor T 1  and the gate electrode G 2  of the second control transistor T 2  are arranged side by side in the first direction Y, thereby further reducing the size of the first control transistor T 1  and the size of the second control transistor T 2  in the second direction X, and optimizing the layout design of the first control transistor T 1  and the second control transistor T 2  in the shift register unit  105 . 
     For example, as shown in  FIGS.  2 A,  4 , and  8   , the gate electrode G 1  of the first control transistor T 1  includes a main body portion G 11  extending along the second direction X and two sub-gate electrodes G 12 , which are parallel to each other, extending from the main body portion G 11  of the gate electrode G 1  of the first control transistor T 1 , that is, the first control transistor T 1  has a double-gate structure. For example, the two sub-gate electrodes G 12 , which are parallel to each other, extend along the first direction Y, respectively. The gate electrode G 2  of the second control transistor T 2  includes a main body portion G 21  extending along the second direction X and two sub-gate electrodes G 22 , which are parallel to each other, extending from the main body portion G 21  of the gate electrode G 2  of the second control transistor T 2 , that is, the second control transistor T 2  has a double-gate structure. For example, the two sub-gate electrodes G 22 , which are parallel to each other, extend along the first direction Y, respectively. 
     Thus, by forming each of the gate electrode G 1  of the first control transistor T 1  and the gate electrode G 2  of the second control transistor T 2  to have a “U”-shaped structure, the stability of the first control transistor T 1  and the stability of the second control transistor T 2  can be improved, thereby improving the performance of the first control transistor T 1  and the performance of the second control transistor T 2 . 
     It should be noted that in some other embodiments of the present disclosure, by taking the first control transistor T 1  as an example, it may also be that the active layer of the first control transistor T 1  has a “U”-shaped structure, the gate electrode of the first control transistor T 1  has a structure in a shape like a Chinese character “—” and overlapping the “U”-shaped active layer, thereby forming a double-gate structure, as long as the gate electrode of the first control transistor T 1  does not affect the arrangement of other structures and does not excessively increase the width of the shift register unit, and the embodiments of the present disclosure are not limited to this case. It should be noted that, it may also be that a single gate electrode overlaps the active layer of the first control transistor T 1 , which is not limited in the embodiments of the present disclosure. 
     For example, as shown in  FIG.  2 A ,  FIG.  4   , and  FIG.  7   , the display substrate further includes a first connection wire L 1 . The first connection wire L 1  extends along the second direction X, an orthographic projection of the first connection wire L 1  on the base substrate  10  is located on a side of an orthographic projection of the gate electrode G 2  of the second control transistor T 2  on the base substrate  10  away from the display region  102 , for example, in the second direction X, the first connection wire L 1  is located on the left side of the gate electrode G 2  of the second control transistor T 2 . A first end L 11  of the first connection wire L 1  is connected to the gate electrode G 2  of the second control transistor T 2 , for example, is connected to the main body portion G 21  of the gate electrode G 2  of the second control transistor T 2 , thereby simplifying the layout structure of the first connection wire L 1 . A second end L 12  of the first connection wire L 1  is connected to the second clock signal line ECB through a hole penetrating the second insulating layer  360  and the third insulating layer  370  to receive the second clock signal provided by the second clock signal line ECB. Thus, the second clock signal provided by the second clock signal line ECB can be transmitted to the gate electrode G 2  of the second control transistor T 2  through the first connection wire L 1 . The first connection wire L 1  and the gate electrode G 2  of the second control transistor T 2  can be integrally formed, thereby simplifying the manufacturing process of the display substrate and reducing the manufacturing cost. 
     For example, as shown in  FIG.  2 A ,  FIG.  7   , and  FIG.  8   , the display substrate further includes a first transfer electrode  110 . The first transfer electrode  110  includes a first sub-portion  111  extending along the first direction Y, a first end  111 A of the first sub-portion  111  of the first transfer electrode  110  is connected to the second electrode SD 12  of the first control transistor T 1 , and is, for example, preferably formed integrally with the second electrode SD 12  of the first control transistor T 1 ; a second end  111 B of the first sub-portion  111  of the first transfer electrode  110  is connected to the second electrode SD 22  of the second control transistor T 2 , and is, for example, preferably formed integrally with the second electrode SD 22  of the second control transistor T 2 . Therefore, the connection between the second electrode SD 12  of the first control transistor T 1  and the second electrode SD 22  of the second control transistor T 2  is achieved through the first transfer electrode  110 . 
     For example, the first transfer electrode  110  may serve as the first node N 1  in the circuit structure as shown in  FIG.  1 B . 
     For example, as shown in  FIGS.  2 A,  3 A,  7 , and  8   , the first power line VGH extends along the first direction Y, an orthographic projection of the first power line VGH on the base substrate  10  is located on a side of the orthographic projection of the active layer A 1  of the first control transistor T 1  on the base substrate  10  and the orthographic projection of the active layer A 2  of the second control transistor T 2  on the base substrate  10  close to the display region  102 , That is, in the second direction X, the first power line VGH is located on the right side of the active layer A 1  of the first control transistor T 1  and the active layer A 2  of the second control transistor T 2 . The display substrate further includes a first power line transfer electrode  180 , and the first power line transfer electrode  180  is connected to and integrally formed with the first power line VGH to transmit the first voltage provided by the first power line VGH. The first electrode SD 11  of the first control transistor T 1  and the first electrode SD 21  of the second control transistor T 2  are respectively connected to the first power line transfer electrode  180 , for example, are preferably formed integrally with the first power line transfer electrode  180 , so that the first electrode SD 11  of the first control transistor T 1  and the first electrode SD 21  of the second control transistor T 2  are respectively connected to the first power line VGH through the first power line transfer electrode  180  to receive the first voltage. 
     For example, a ratio between a width of the first power line VGH in the second direction X and a width of the first clock signal line ECK in the second direction X is greater than or equal to 1.2 and less than or equal to 3, That is, the width of the first power line VGH in the second direction X may be 1.2 to 3 times the width of the first clock signal line ECK in the second direction X; a ratio between the width of the first power line VGH in the second direction X and a width of the second clock signal line ECB in the second direction X is greater than or equal to 1.2 and less than or equal to 3, that is, the width of the first power line VGH in the second direction X may be 1.2 to 3 times the width of the second clock signal line ECB in the second direction X. As a result, the stability of the signal transmitted on the first power line VGH is improved, and the charging time is reduced. 
     For example, the width of the first power line VGH in the second direction X may be 1.1 times, 1.2 times, 1.33 times, 1.5 times, 1.8 times, 2 times, 2.2 times, 2.5 times, 2.7 times, or 3 times the width of the first clock signal line ECK in the second direction X, or the like; the width of the first power line VGH in the second direction X may be 1.1 times, 1.2 times, 1.33 times, 1.5 times, 1.8 times, 2 times, 2.2 times, 2.5 times, 2.7 times, or 3 times the width of the second clock signal line ECB in the second direction X, or the like. 
     For example, as shown in  FIG.  2 A ,  FIG.  3 A , and  FIG.  7   , the display substrate further includes a second transfer electrode  120 . An orthographic projection of the second transfer electrode  120  on the base substrate  10  is located on a side of the orthographic projection of the active layer A 1  of the first control transistor T 1  on the base substrate  10  and the orthographic projection of the active layer A 2  of the second control transistor T 2  on the base substrate  10  away from the display region  102 , that is, in the second direction X, the second transfer electrode  120  is located on the left side of the active layer A 1  of the first control transistor T 1  and the active layer A 2  of the second control transistor T 2 . The second transfer electrode  120  extends along the first direction Y and is connected to the gate electrode G 1  of the first control transistor T 1  through a hole penetrating the second insulating layer  360  and the third insulating layer  370 , for example, is connected to the main body portion G 11  of the gate electrode G 1  of the first control transistor T 1 . 
     For example, in the K-th stage of shift register unit  105 , the second transfer electrode  120  is connected to the output terminal EOUT of the previous stage of shift register unit to receive an input signal. 
     For example, in the case where the shift register unit  105  is a first stage of shift register unit, the second transfer electrode  120  is connected to the trigger signal line ESTV, so that the trigger signal provided by the trigger signal line ESTV is used as the input signal of the current stage of shift register unit. 
     For example, as shown in  FIGS.  2 A and  3 A , an orthographic projection of an active layer A 7  of the output transistor T 7  on the base substrate  10  and an orthographic projection of an active layer A 8  of the output control transistor T 8  on the base substrate  10  are located on a side of the orthographic projection of the active layer A 1  of the first control transistor T 1  on the base substrate  10  and the orthographic projection of the active layer A 2  of the second control transistor T 2  on the base substrate  10  close to the display region  102 , and is located on a side of the orthographic projection of the first power line VGH on the base substrate  10  away from the display region  102 . That is, in the second direction X, the active layer A 7  of the output transistor T 7  and the active layer A 8  of the output control transistor T 8  are located between the first power line VGH and the active layer A 1  of the first control transistor T 1  as well as the active layer A 2  of the second control transistor T 2 . 
     For example, as shown in  FIGS.  2 A and  3 A , the display substrate includes at least one common semiconductor pattern, for example, the at least one common semiconductor pattern includes a plurality of common semiconductor patterns CSP. The active layer A 7  of the output transistor T 7  and the active layer A 8  of the output control transistor T 8  are different portions of the plurality of common semiconductor patterns CSP, respectively, thereby improving the stability of the output transistor T 7  and the stability of the output control transistor T 8 . 
     For example, the plurality of common semiconductor patterns CSP are spaced apart from each other and arranged in parallel in the second direction X. Or, in some other embodiments of the present disclosure, the plurality of common semiconductor patterns CSP may also be continuously arranged in the second direction X to form a common semiconductor pattern, and the embodiments of the present disclosure are not limited to this case. 
     For example, in the first direction Y, the active layer A 7  of the output transistor T 7  is located below the active layer A 8  of the output control transistor T 8 , so that the active layer A 7  of the output transistor T 7  and the active layer A 8  of the output control transistor T 8  are arranged side by side in the first direction Y, thereby reducing the size of the active layer A 7  of the output transistor T 7  and the size of the active layer A 8  of the output control transistor T 8  in the second directions X. 
     For example, as shown in  FIGS.  2 A and  4   , the gate electrode G 7  of the output transistor T 7  includes a plurality of sub-gate electrodes G 71  connected in parallel, and the plurality of sub-gate electrodes G 71  of the output transistor T 7  are parallel to each other in the first direction Y. For example, each sub-gate electrode G 71  of the output transistor T 7  extends in the second direction X, so that the gate electrode G 7  of the output transistor T 7  is comb-shaped in the first direction Y, thereby improving the stability of the output transistor T 7 . The gate electrode G 8  of the output control transistor T 8  includes a plurality of sub-gate electrodes G 81  connected in parallel, and the plurality of sub-gate electrodes G 81  of the output control transistor T 8  are parallel to each other in the first direction Y. For example, each sub-gate electrode G 81  of the output control transistor T 8  extends in the second direction X, so that the gate electrode G 8  of the output control transistor T 8  is comb-shaped in the first direction Y, thereby improving the stability of the output control transistor T 8 . 
     For example, as shown in  FIGS.  2 A,  3 A, and  7   , the display substrate further includes a third transfer electrode  130  and a second power line transfer electrode  190 . The second power line VGL extends along the first direction Y, an orthographic projection of the second power line VGL on the base substrate  10  is located on a side of the orthographic projection of the active layer A 1  of the first control transistor T 1  on the base substrate  10  and the orthographic projection of the active layer A 2  of the second control transistor T 2  on the base substrate  10  away from the display region  102 , that is, in the second direction X, the second power line VGL is located on the left side of the active layer A 1  of the first control transistor T 1  and the active layer A 2  of the second control transistor T 2 . The second power line transfer electrode  190  is connected to and is integrally formed with the second power line VGL, thereby transmitting the second voltage provided by the second power line VGL. The first electrode of the output transistor T 7  is connected to the second power line VGL through the second power line transfer electrode  190  to receive the second voltage. The first electrode of the output control transistor T 8  is connected to the first power line transfer electrode  180 , and is, for example, preferably formed integrally with the first power line transfer electrode  180 , so that the first electrode of the output control transistor T 8  is connected to the first power line VGH through the first power line transfer electrode  180  to receive the first voltage. The second electrode of the output transistor T 7  is connected to the third transfer electrode  130 , for example, is preferably formed integrally with the third transfer electrode  130 , the second electrode of the output control transistor T 8  is connected to the third transfer electrode  130 , for example, is preferably formed integrally with the third transfer electrode  130 , the output terminal EOUT includes the third transfer electrode  130 , that is, the second electrode of the output transistor T 7  and the second electrode of the output control transistor T 8  are respectively connected to the output terminal EOUT through the third transfer electrode  130  to provide the output signal. 
     For example, the ratio between the width of the second power line VGL in the second direction X and the width of the first clock signal line ECK in the second direction X is greater than or equal to 1.2 and less than or equal to 3, that is, the width of the second power line VGL in the second direction X may be 1.2 to 3 times the width of the first clock signal line ECK in the second direction X; the ratio between the width of the second power line VGL in the second direction X and the width of the second clock signal line ECB in the second direction X is greater than or equal to 1.2 and less than or equal to 3, that is, the width of the second power line VGL in the second direction X may be 1.2 to 3 times the width of the second clock signal line ECB in the second direction X. As a result, the stability of the signal transmitted on the second power line VGL is improved, and the charging time is reduced. 
     For example, the width of the second power line VGL in the second direction X may be 1.1 times, 1.2 times, 1.33 times, 1.5 times, 1.8 times, 2 times, 2.2 times, 2.5 times, 2.7 times, or 3 times the width of the first clock signal line ECK in the second direction X, and the like, and the width of the second power line VGL in the second direction X may be 1.1 times, 1.2 times, 1.33 times, 1.5 times, 1.8 times, 2 times, 2.2 times, 2.5 times, 2.7 times, or 3 times the width of the second clock signal line ECB in the second direction X, and the like. 
     For example, as shown in  FIGS.  2 A,  3 A, and  7   , the orthographic projection of the first capacitor C 1  on the base substrate  10  is located between the orthographic projection of the active layer A 7  of the output transistor T 7  on the base substrate  10  and the orthographic projection of the first power line VGH on the base substrate  10 , and is arranged side by side in the second direction X with the orthographic projection of the active layer A 7  of the output transistor T 7  on the base substrate  10 , that is, in the second direction X, the first capacitor C 1  is located between the active layer A 7  of the output transistor T 7  and the first power line VGH. The orthographic projection of the second capacitor C 2  on the base substrate  10  is located between the orthographic projection of the active layer A 8  of the output control transistor T 8   on the base substrate  10  and the orthographic projection of the first power line VGH on the base substrate  10 , and is arranged side by side in the second direction X with the orthographic projection of the active layer of the output control transistor T 8  on the base substrate  10 , that is, in the second direction X, the second capacitor C 2  is located between the active layer A 8  of the output control transistor T 8  and the first power line VGH. For example, the first capacitor C 1  and the second capacitor C 2  may partially overlap with the first power line VGH, respectively. The orthographic projection of the first capacitor C 1  on the base substrate  10  and the orthographic projection of the second capacitor C 2  on the base substrate  10  are arranged side by side in the first direction Y, that is, the first capacitor C 1  and the second capacitor C 2  are arranged in the first direction Y. For example, in the first direction Y, the second capacitor C 2  is located above the first capacitor C 1 . 
     Therefore, by arranging the first capacitor C 1  and the second capacitor C 2  side by side in the first direction Y, the number of devices arranged side by side in the second direction X can be further reduced, so that the space occupied by the first capacitor C 1  and the second capacitor C 2  in the second direction X can be reduced, furthermore, the size of the shift register unit  105  in the second direction X is compressed to a certain extent, which is conducive to the implementation of the narrow frame design of the display substrate and ensures the display quality of the display substrate at the same time. 
     For example, as shown in  FIG.  2 A ,  FIG.  4   , and  FIG.  5   , the first electrode CE 11  of the first capacitor C 1  is connected to and formed integrally with the gate electrode G 7  of the output transistor T 7 , thereby forming, for example, a comb-like structure. The second electrode CE 21  of the first capacitor C 1  is connected to the third transfer electrode  130  through a hole penetrating the third insulating layer  370 . The first electrode CE 12  of the second capacitor C 2  is connected to and integrally formed with the gate electrode G 8  of the output control transistor T 8 , thereby forming, for example, a comb-like structure. The second electrode CE 22  of the second capacitor C 2  is connected to the first power line VGH through the hole penetrating the third insulating layer  370  to receive the first voltage. 
     For example, as shown in  FIGS.  2 A and  3 A , the active layer A 3  of the third control transistor T 3  extends along the second direction X. For example, in conjunction with  FIG.  2 A ,  FIG.  2 B , and  FIG.  3 A , a minimum distance in the second direction X between the orthographic projection of the active layer A 3  of the third control transistor T 3  on the base substrate  10  and the orthographic projections of the first clock signal line ECK and the second clock signal line ECB on the base substrate  10  is a third distance. For example, the third distance D3 is a spacing distance in the second direction X between the orthographic projection of the active layer A 3  of the third control transistor T 3  on the base substrate  10  and an edge of the side of the first clock signal line ECK close to the display region  102 . The difference between the first distance D1 and the third distance D3 is greater than or equal to 0 and less than or equal to twice the size AL1 of the active layer A 1  of the first control transistor T 1  in the second direction X or twice the size AL3 of the active layer A 3  of the third control transistor T 3  in the second direction X, that is, 0≤ | D1-D3 | ≤2AL1 or 0≤ | D1-D3 | ≤2AL3. The difference between the second distance D2 and the third distance D3 is greater than or equal to 0 and less than or equal to twice the size AL2 of the active layer A 2  of the second control transistor T 2  in the second direction X or twice the size AL3 of the active layer A 3  of the third control transistor T 3  in the second direction X, that is, 0≤ | D2-D3 | ≤2AL2 or 0≤ | D2-D3 | ≤2AL3. For example, AL3 is the length of the active layer A 3  of the third control transistor T 3  in the second direction X. Thus, the active layer A 1  of the first control transistor T 1 , the active layer A 2  of the second control transistor T 2 , and the active layer A 3  of the third control transistor T 3  are arranged side by side in the first direction Y. 
     For example, the orthographic projection of the active layer A 3  of the third control transistor T 3  on the base substrate  10  is located on the side of the orthographic projections of the first clock signal line ECK and the second clock signal line ECB on the base substrate  10  close to the display region  102 . For example, the orthographic projection of the active layer A 3  of the third control transistor T 3  on the base substrate  10  is located on the side of the orthographic projection of the active layer A 2  of the second control transistor T 2  on the base substrate  10  away from the orthographic projection of the active layer A 1  of the first control transistor T 1  on the base substrate  10 . That is, the active layer A 1  of the first control transistor T 1 , the active layer A 2  of the second control transistor T 2 , and the active layer A 3  of the third control transistor T 3  are sequentially arranged in the first direction Y from top to bottom. 
     Thus, by arranging the active layer A 1  of the first control transistor T 1 , the active layer A 2  of the second control transistor T 2 , and the active layer A 3  of the third control transistor T 3  side by side in the first direction Y, the size of the active layer A 1  of the first control transistor T 1 , the size of the active layer A 2  of the second control transistor T 2 , and the size of the active layer A 3  of the third control transistor T 3  in the second direction X can be reduced, and therefore, the layout design of the first control transistor T 1 , the second control transistor T 2 , and the third control transistor T 3  in the shift register unit  105  is optimized. Furthermore, the size of the shift register unit  105  in the second direction X is reduced to a certain extent, the space required by the shift register unit  105  in the peripheral region  106  of the display substrate is reduced, which is beneficial to achieve the narrow frame design of the display substrate and ensure the display quality of the display substrate as the same time. In addition, more sufficient space can be reserved for other transistors, capacitors, wires, etc. in the shift register unit  105 , so that the wiring connection and the structural layout of the shift register unit  105  can be further optimized. 
     For example, as shown in  FIGS.  2 A and  4   , the gate electrode G 1  of the first control transistor T 1 , the gate electrode G 2  of the second control transistor T 2 , and the gate electrode G 3  of the third control transistor T 3  are parallel to each other in the first direction Y. That is, the gate electrode G 1  of the first control transistor T 1 , the gate electrode G 2  of the second control transistor T 2 , and the gate electrode G 3  of the third control transistor T 3  are sequentially arranged in the first direction Y from top to bottom. Thus, the size of the first control transistor T 1 , the size of the second control transistor T 2 , and the size of the third control transistor T 3  in the second direction X are further reduced, and the layout design of the first control transistor T 1 , the second control transistor T 2 , and the third control transistor T 3  in the shift register unit  105  is optimized. 
     For example, as shown in  FIGS.  2 A and  4   , the orthographic projection of the third capacitor C 3  on the base substrate  10  is located between the orthographic projection of the active layer A 3  of the third control transistor T 3  on the base substrate  10  and the orthographic projection of the active layer A 2  of the second control transistor T 2  on the base substrate  10  in the first direction Y. That is, in the first direction Y, the third capacitor C 3  is located between the active layer A 3  of the third control transistor T 3  and the active layer A 2  of the second control transistor T 2 , thereby further reducing the size of the shift register unit  105   in the second direction X to a certain extent. 
     For example, as shown in  FIG.  2 A ,  FIG.  4   ,  FIG.  5   , and  FIG.  7   , the first transfer electrode  110  further includes a second sub-portion  112  extending along the second direction X, an end of the second sub-portion  112  of the first transfer electrode  110  is connected to the first electrode CE 13  of the third capacitor C 3  through a hole penetrating the second insulating layer  360  and the third insulating layer  370 . The first electrode CE 13  of the third capacitor C 3  is connected to and is formed integrally with the gate electrode G 3  of the third control transistor T 3 , and the second electrode CE 23  of the third capacitor C 3  is connected to and is formed integrally with the electrode connection wire M 1 , thereby simplifying the manufacturing process of the display substrate and reducing the manufacturing cost. The electrode connection wire M 1  extends along the second direction X. A first end M 11  of the electrode connection wire M 1  is connected to the first clock signal line ECK through a hole penetrating the third insulating layer  370  to receive the first clock signal; a second end M 12  of the electrode connection wire M 1  is connected to the second electrode CE 23  of the third capacitor C 3  to transmit the first clock signal provided by the first clock signal line ECK. The display substrate further includes a fourth transfer electrode  140 , and the fourth transfer electrode  140  extends along the first direction Y to reduce the size occupied by the fourth transfer electrode  140  in the second direction X. A first end  141  of the fourth transfer electrode  140  is connected to the second end M 12  of the electrode connection wire M 1  through a hole penetrating the third insulating layer  370 , and a second end  142  of the fourth transfer electrode  140  is connected to the first electrode of the third control transistor T 3 , and is, for example, preferably formed integrally with the first electrode of the third control transistor T 3 . Thus, the first clock signal provided by the first clock signal line ECK is transmitted through the fourth transfer electrode  140  and the electrode connection wire M 1 . 
     For example, as shown in  FIGS.  2 A and  3 A , the active layer A 4  of the fourth control transistor T 4  extends along the second direction X, and the orthographic projection of the active layer A 4  of the fourth control transistor T 4  on the base substrate  10  is located on a side of the orthographic projection of the active layer A 3  of the third control transistor T 3  on the base substrate  10  away from the orthographic projection of the active layer A 2  of the second control transistor T 2  on the base substrate  10  in the first direction Y. 
     For example, in conjunction with  FIG.  2 A ,  FIG.  2 B , and  FIG.  3 A , a minimum distance in the second direction X between the orthographic projection of the active layer A 4  of the fourth control transistor T 4  on the base substrate  10  and the orthographic projections of the first clock signal line ECK and the second clock signal line ECB on the base substrate  10  is a fourth distance D4. For example, the fourth distance D4 is a spacing distance in the second direction X between the orthographic projection of the active layer A 4  of the fourth control transistor T 4  on the base substrate  10  and an edge of the side of the first clock signal line ECK close to the display region  102 . The difference between the third distance D3 and the fourth distance D4 is greater than or equal to 0 and less than or equal to the size AL3 of the active layer A 3  of the third control transistor T 3  in the second direction X or the size AL4 of the active layer A 4  of the fourth control transistor T 4  in the second direction X, that is, 0≤ | D3-D4 | ≤AL3 or 0≤ | D3-D4 | ≤AL4. For example, AL4 is the length of the active layer A 4  of the fourth control transistor T 4  in the second direction X. Thus, the active layer A 2  of the second control transistor T 2 , the active layer A 3  of the third control transistor T 3 , and the active layer A 4  of the fourth control transistor T 4  are sequentially arranged in the first direction Y from top to bottom, thereby further optimizing the layout structure of the second control transistor T 2 , the third control transistor T 3 , and the fourth control transistor T 4  in the display substrate, and reducing the size of the shift register unit  105  in the second direction X to a certain extent. 
     For example, as shown in  FIG.  2 A ,  FIG.  4   , and  FIG.  7   , the display substrate further includes a fifth transfer electrode  150  and a second connection wire L 2 . The fifth transfer electrode  150  extends along the second direction X, a first end  151  of the fifth transfer electrode  150  is connected to the second electrode of the third control transistor T 3 , and is, for example, preferably formed integrally with the second electrode of the third control transistor T 3 , and a second end  152  of the fifth transfer electrode  150  is connected to the first electrode of the fourth control transistor T 4 , and is, for example, preferably formed integrally with the first electrode of the fourth control transistor T 4 . A first end L 21  of the second connection wire L 2  is connected to the fifth transfer electrode  150  through a hole penetrating the second insulating layer  360  and the third insulating layer  370 , and a second end L 22  of the second connection wire L 2  is connected to the gate electrode G 8  of the output control transistor T 8 . The second connection wire L 2  can be formed integrally with the gate electrode G 8  of the output control transistor T 8  to simplify the manufacturing process of the display substrate. The second electrode of the fourth control transistor T 4  is connected to the first power line transfer electrode  180 , and is, for example, preferably formed integrally with the first power line transfer electrode  180 , to receive the first voltage. 
     For example, as shown in  FIGS.  2 A and  3 A , the active layer A 6  of the input transistor T 6  and the active layer A 5  of the fifth control transistor T 5  respectively extend along the first direction Y and are arranged side by side in the second direction X, thereby reducing the size of the active layer A 6  of the input transistor T 6  and the size of the active layer A 5  of the fifth control transistor T 5  in the second direction X. The orthographic projection of the active layer A 6  of the input transistor T 6  on the base substrate  10  and the orthographic projection of the active layer A 5  of the fifth control transistor T 5  on the base substrate  10  are located on the side of the orthographic projection of the active layer A 4  of the fourth control transistor T 4  on the base substrate  10  away from the orthographic projection of the active layer A 3  of the third control transistor T 3  on the base substrate  10 . That is, the active layer A 6  of the input transistor T 6  and the active layer A 5  of the fifth control transistor T 5  are located below the active layer A 4  of the fourth control transistor T 4  in the first direction Y. 
     For example, in conjunction with  FIG.  2 A ,  FIG.  2 B , and  FIG.  3 A , a minimum distance in the second direction X between the orthographic projection of the active layer A 6  of the input transistor T 6  on the base substrate  10  and the orthographic projections of the first clock signal line ECK and the second clock signal line ECB on the base substrate  10  is a fifth distance D5. For example, the fifth distance D5 is a spacing distance in the second direction X between the orthographic projection of the active layer A 6  of the input transistor T 6  on the base substrate  10  and an edge of the side of the first clock signal line ECK close to the display region  102 . A difference between the fourth distance D4 and the fifth distance D5 is greater than or equal to 0 and less than or equal to 1.5 times the size of the active layer A 4  of the fourth control transistor T 4  in the second direction X, that is, 0≤ | D4-D5 | ≤1.5AL4. Therefore, the layout setting of the input transistor T 6  in the first direction Y and the second direction X is further optimized. 
     For example, in conjunction with  FIGS.  2 A,  2 B and  3 A , a minimum distance in the first direction Y between the orthographic projection of the active layer A 6  of the input transistor T 6  on the base substrate  10  and the orthographic projection of the active layer A 4  of the fourth control transistor T 4  on the base substrate  10  is a sixth distance D6, and a minimum distance in the first direction Y between the orthographic projection of the active layer A 5  of the fifth control transistor T 5  on the base substrate  10  and the orthographic projection of the active layer A 4  of the fourth control transistor T 4  on the base substrate  10  is a seventh distance D 7 . A difference between the sixth distance D6 and the seventh distance D 7  is greater than or equal to 0 and less than or equal to the size AL6 of the active layer A 6  of the input transistor T 6  in the first direction Y or the size AL5 of the active layer A 5  of the fifth control transistor T 5  in the first direction Y, that is, 0≤ | D6-D7 | ≤AL5 or 0≤ | D6-D7 | ≤AL6. For example, AL5 is the length of the active layer A 5  of the fifth control transistor T 5  in the first direction Y, and AL6 is the length of the active layer A 6  of the input transistor T 6  in the first direction Y. Therefore, the layout settings of the fifth control transistor T 5  and the input transistor T 6  in the first direction Y is further optimized. 
     For example, in some other embodiments of the present disclosure, as shown in  FIG.  3 B , the active layer A 6  of the input transistor T 6  and the active layer A 5  of the fifth control transistor T 5  may also extend along the second direction X and be arranged side by side in the first direction Y, as a result, the active layer A 1  of the first control transistor T 1 , the active layer A 2  of the second control transistor T 2 , the active layer A 3  of the third control transistor T 3 , the active layer A 4  of the fourth control transistor T 4 , the active layer A 6  of the input transistor T 6 , and the active layer A 5  of the fifth control transistor T 5  in the shift register unit  105  extend along the second direction X and are arranged in sequence in the first direction Y, thereby simplifying the manufacturing process of the display substrate, for example, simplifying the manufacturing process of the active layer of the display substrate and reducing the manufacturing cost. 
     For example, in the case where the active layer A 6  of the input transistor T 6  and the active layer A 5  of the fifth control transistor T 5  respectively extend along the second direction X, the active layer A 6  of the input transistor T 6  may be located above the active layer A 5  of the fifth control transistor T 5  as shown in  FIG.  3 B , that is, the orthographic projection of the active layer A 5  of the fifth control transistor T 5  on the base substrate  10  is located on the side of the orthographic projection of the active layer A 6  of the input transistor T 6  on the base substrate  10  away from the orthographic projection of the active layer A 4  of the fourth control transistor T 4  on the base substrate  10 ; alternatively, the active layer A 6  of the input transistor T 6  may also be located below the active layer A 5  of the fifth control transistor T 5 , that is, the orthographic projection of the active layer A 5  of the fifth control transistor T 5  on the base substrate  10  is located on the side of the orthographic projection of the active layer A 6  of the input transistor T 6  on the base substrate  10  close to the orthographic projection of the active layer A 4  of the fourth control transistor T 4  on the base substrate  10 , and the embodiments of the present disclosure are not limited to this case. 
     For example, as shown in  FIG.  2 A ,  FIG.  4   , and  FIG.  7   , the display substrate further includes a sixth transfer electrode  160 , a seventh transfer electrode  170 , a third connection wire L 3 , and a fourth connection wire L 4 . The first electrode of the input transistor T 6  is connected to the first end  161  of the sixth transfer electrode  160 , and is, for example, preferably formed integrally with the first end  161  of the sixth transfer electrode  160 , and the second electrode of the input transistor T 6  is connected to the second transfer electrode  120 , and is preferably formed integrally with the second transfer electrode  120 , for example. The third connection wire L 3  extends along the second direction X, a first end L 31  of the third connection wire L 3  is connected to the first clock signal line ECK through a hole penetrating the second insulating layer  360  and the third insulating layer  370  to receive the first clock signal provided by the first clock signal line ECK. A second end L 32  of the third connection wire L 3  is connected to the gate electrode G 6  of the input transistor T 6  to transmit the first clock signal. The third connection wire L 3  is formed integrally with the gate electrode G 6  of the input transistor T 6 , thereby simplifying the manufacturing process of the display substrate and reducing the manufacturing cost. The gate electrode G 5  of the fifth control transistor T 5  is connected to the second power line transfer electrode  190  through a hole penetrating the second insulating layer  360  and the third insulating layer  370  to receive the second voltage. The first electrode of the fifth control transistor T 5  is connected to the second end  162  of the sixth transfer electrode  160 , and is, for example, preferably formed integrally with the second end  162  of the sixth transfer electrode  160 ; the second electrode of the fifth control transistor T 5  is connected to the first end  171  of the seventh transfer electrode  170 , and is, for example, preferably formed integrally with the first end  171  of the seventh transfer electrode  170 , the second end  172  of the seventh transfer electrode  170  is connected to the first end L 41  of the fourth connection wire L 4  through a hole penetrating the second insulating layer  360  and the third insulating layer  370 , and the second end L 42  of the fourth connection wire L 4  is connected to the gate electrode G 7  of the output transistor T 7 . For example, the fourth connection wire L 4  can be formed integrally with the gate electrode G 7  of the output transistor T 7  to simplify the manufacturing process. 
     For example, as shown in  FIG.  7   , the sixth transfer electrode  160  extends along the second direction X, so that the layout design between the first electrode of the fifth control transistor T 5  and the first electrode of the input transistor T 6  can be optimized. 
     For example, in some embodiments of the present disclosure, the display substrate further includes a gate drive circuit (not shown in the figure). The gate drive circuit includes a plurality of shift register units that are cascaded. For example, the gate drive circuit is the reset control drive circuit array described above, which includes a plurality of shift register units  105  that are cascaded, so that the reset control signals can be output row by row. 
     For example, the trigger signal line ESTV is configured to provide a trigger signal to the gate drive circuit, the orthographic projection of the trigger signal line ESTV on the base substrate  10  is located on the side of the orthographic projections of the first clock signal line ECK and the second clock signal line ECB on the base substrate  10  away from the display region  102 , that is, in the second direction X, the trigger signal line ESTV is located on the left side of the first clock signal line ECK and the second clock signal line ECB. The trigger signal line ESTV is connected to the input circuit of the first stage of shift register unit of the gate drive circuit to provide a trigger signal as the input signal of the first stage of shift register unit. For specific introduction, please refer to the previous description, which will not be repeated here. 
     For example, in some embodiments of the present disclosure, the line width of the wire of each layer is generally 3 micrometers, for example, and the spacing distance between the wires on the same layer is, for example, greater than 3 micrometers. For example, the spacing distance between the wires is related to the accuracy of the exposure machine, for example, the higher the accuracy of the exposure machine, the smaller the spacing distance can be, the details can be specifically determined according to the actual situations, and the embodiments of the present disclosure are not limited to this case. In the embodiments of the present disclosure, necessary spacing must be left between the wires in the same layer to avoid the wire adhesion, signal short circuit, etc. in the actual process. 
     A distance between an orthographic projection of a wire of the first conductive layer  320  on the base substrate  10  and an orthographic projection of a wire of the second conductive layer  330  on the base substrate  10  is generally 1.5 micrometers, for example. For example, a gate electrode of a transistor in the first conductive layer  320  needs to exceed an active layer of the transistor on the semiconductor layer  310  by more than 2 micrometers, for example. For example, as shown in  FIGS.  2 A,  3 A, and  4   , the “U″-shaped double gate of the first control transistor T 1  extends, in the first direction Y, beyond the active layer of the first control transistor T 1  by, for example, more than 2 micrometers on both sides of the active layer of the first control transistor T 1 , for example, a length of a portion of the “U”-shaped double gate of the first control transistor T 1  that does not overlap the active layer of the first control transistor T 1  in the first direction Y is 2 micrometers or more, and the embodiments of the present disclosure are not limited to this case. 
     For example, a spacing distance between an orthographic projection of an active layer of each transistor in the semiconductor layer  310  on the base substrate  10  and an orthographic projection of each gate wire in the first conductive layer  320  on the base substrate  101  is 1.5 micrometers or more, so as to avoid a channel effect between the gate wire and the active layer of each transistor in the semiconductor layer  310  from occurring. For example, the spacing distance between the orthographic projection of the semiconductor layer  310  on the base substrate  10  and the orthographic projection of the second conductive layer  330  on the base substrate  10  is not limited, for example, the orthographic projection of the semiconductor layer  310  on the base substrate  10  and the orthographic projection of the second conductive layer  330  on the base substrate  10  may be overlapped. For example, in some embodiments of the present disclosure, a certain spacing distance between wires in different layers is reserved as much as possible (this spacing distance is smaller than the spacing distance between wires in the same layer), thereby reducing unnecessary overlap, and reducing or avoiding interference caused by excessive parasitic capacitance. 
     For example, a width of each wire of the third conductive layer  340  should cover (for example, completely cover) a hole corresponding to the wire, for example, the wire may exceed the size of the hole (for example, the diameter of the hole) by more than 1 micron, for example, the size of the hole is 2.0 µm~2.5 µm, and the width of each wire of the third conductive layer  340  that covers the hole is 4 µm~5 µm. For example, the width of the wire, corresponding to the hole, of the output transistor T 7  and the output control transistor T 8  exceeds the size of the hole by 1 micron above and below, for example, 4.0~4.5 micron. Because the output transistor T 7  and the output control transistor T 8  correspond to many holes, the width of the wire, connecting other transistors, in the third conductive layer  340  only needs to meet the requirement of covering the hole by more than 1 micron at the position of the hole. For example, the width of the wire between the holes can be relatively narrow. 
     For example, the spacing distance between the first clock signal line ECK, the second clock signal line ECB, the first power line VGH, and the second power line VGL, and the like located on the third conductive layer  340  is 3 microns or more, in order to meet the driving capability requirement, a line width of the first clock signal line ECK and a line width of the second clock signal line ECB are set to be 9 microns or more, a line width of the first power line VGH and a line width of the second power line VGL can be 6 micrometers, 9 micrometers, or 10 micrometers, or the like. The second voltage provided by the second power line VGL may be -7 V, for example. 
     For example, in some examples, the thickness of the first conductive layer  320  and the thickness of the second conductive layer  330  are 2000 \~300 angstroms, the thickness of the third conductive layer  340  is 5000 \~8000 angstroms, and the embodiments of the present disclosure are not limited to this case. 
     For example, by arranging the above-mentioned transfer electrodes, connection wires, electrode connection wires, etc., problems such as wire adhesion and signal short circuit caused by dense wires in the same layer can be reduced or avoided. For example, the above-mentioned transfer electrodes, connection wires, electrode connection wires, and the like can play a role in connections or jumper connections. 
     The display substrate provided by the above-mentioned embodiments of the present disclosure optimizes the circuit connection and structural layout of the shift register unit, reduces the size of the shift register unit in the second direction to a certain extent, and reduces the space that the shift register unit needs to occupy in the peripheral region of the display substrate, which is beneficial to achieve the narrow frame design by using the display substrate, and ensure the display quality achieved by using the display substrate. 
     At least one embodiment of the present disclosure also provides a display device.  FIG.  9    is a schematic diagram of a display device provided by at least one embodiment of the present disclosure.

The display device 2 may also include other components, such as a data drive circuit, a timing controller, etc., and the embodiments of the present disclosure are not limited to this case. 
     It should be noted that, for the sake of clarity and conciseness, the embodiments of the present disclosure do not provide all the constituent units of the display device 2. In order to achieve the basic function of the display device 2, those skilled in the art can provide and set other structures not shown according to specific needs, which are not limited in the embodiments of the present disclosure.

     At least one embodiment of the present disclosure also provides a manufacturing method of a display substrate, for example, the manufacturing method of the display substrate provided by any embodiment of the present disclosure.  FIG.  10    is a flowchart of a manufacturing method of a display substrate provided by at least one embodiment of the present disclosure. For example, the manufacturing method can be used to manufacture the display substrate provided by any embodiment of the present disclosure, for example, can be used to manufacture the display substrate as shown in  FIG.  2    above. 
     As shown in  FIG.  10   , the manufacturing method of the display substrate includes the following steps S 10  to S 20 . 
     Step S 10 : providing a base substrate. 
     Step S 20 : forming a shift register unit, a first power line for providing a first voltage, a second power line for providing a second voltage, a first clock signal line, and a second clock signal line on the base substrate. 
     For example, forming a semiconductor layer, a first insulating layer, a first conductive layer, a second insulating layer, a second conductive layer, a third insulating layer, and a third conductive layer respectively includes forming corresponding material layers (for example, a semiconductor material layer, an insulating material layer, or a conductive material layer), and then using a patterning process to form corresponding pattern structures (for example, active layers, electrode patterns, wires, holes, etc.). The patterning process is, for example, a photolithography process, including: coating a photoresist layer on the insulating material that needs to be patterned, using a mask to expose the photoresist layer, developing the exposed photoresist layer to obtain a photoresist pattern, etching the structure layer using the photoresist pattern, and then optionally removing the photoresist pattern. 
     For example, taking the case of manufacturing the display substrate as shown in  FIG.  2 A  as an example, for step S 10 , the base substrate  101  can be made of, for example, glass, plastic, quartz, or other suitable materials, and the embodiments of the present disclosure are not limited to this case. 
     For example, the shift register unit  105 , the first power line VGH, the second power line VGL, the first clock signal line ECK, and the second clock signal line ECB are formed on the base substrate  10 . 
     For step S 20 , for example, forming the shift register unit  105  includes: sequentially forming a semiconductor layer  310 , a first insulating layer  350 , a first conductive layer  320 , a second insulating layer  360 , a second conductive layer  330 , a third insulating layer  370 , and a third conductive layer  340  in a direction perpendicular to the base substrate  10 . Active layers of respective transistors are located on the semiconductor layer  310 , gate electrodes of the respective transistor and first electrodes of respective capacitors are located on the first conductive layer  320 , second electrodes of the respective capacitors are located on the second conductive layer  330 , and the first power line VGH, the second power line VGL, the first clock signal line ECK, the second clock signal line ECB, and first electrodes and second electrodes of the respective transistors are on the third conductive layer  340 . 
     For example, the respective transistors and the respective capacitors are connected to each other and are connected to the first power line VGH, the second power line VGL, the first clock signal line ECK, and the second clock signal ECB through holes penetrating the first insulating layer  350 , the second insulating layer  360 , or the third insulating layer  370 .
