As shown in  FIG. 1  and  FIG. 2 , an electronic device  100  is provided by the present disclosure, wherein the electronic device  100  may for example include a laptop, public display, tiled display, vehicle display, touch display, television, surveillance camera, smart phone, tablet, light source module, lighting device or the electronic devices applied to the above-mentioned products, but not limited thereto.

In the following embodiments, a display device is taken as an example of the electronic device  100  for description, but the present disclosure is not limited thereto. In the present embodiment, as shown in  FIG. 1 , the electronic device  100  may include a first substrate SB 1 , a second substrate SB 2 , a first functional layer FL 1  and a second functional layer FL 2 , but not limited thereto. The first substrate SB 1  has a first surface SF 1 , a first side-surface SSF 1  adjacent to the first surface SF 1 , and an outer surface RS opposite to the first surface SF 1 . For example, the first side-surface SSF 1  is located between the first surface SF 1  and the outer surface RS. The second substrate SB 2  has a second surface SF 2  and a second side-surface SSF 2  adjacent to the second surface SF 2 . For example, the second surface SF 2  may connect to the second side-surface SSF 2 . The first substrate SB 1  and the second substrate SB 2  are disposed opposite to each other and may include rigid substrates or flexible substrates, wherein the rigid substrate may include glass, quartz, sapphire, ceramic, other suitable materials or the combinations of any the above-mentioned materials, and the flexible substrate may include polyimide (PI) substrate, polycarbonate (PC) substrate, polyethylene terephthalate (PET) substrate, other suitable substrates or the combinations of the above-mentioned substrates, but not limited thereto. The first functional layer FL 1  may be disposed on the first substrate SB 1 . Specifically, the first functional layer FL 1  is disposed on the first surface SF 1  (i.e., an inner surface) of the first substrate SB 1 . The first functional layer FL 1  of the present embodiment may include a plurality of driving elements and/or driving circuits (such as thin film transistor (TFT) elements) electrically connected to the light emitting elements of the electronic device  100  to drive the light emitting elements, but not limited thereto.

The second functional layer FL 2  is disposed on the second substrate SB 2 . Specifically, the second functional layer FL 2  is disposed on a second surface SF 2  (i.e., an inner surface) of the second substrate SB 2 . The second functional layer FL 2  of the present embodiment may include color filters, a black matrix and/or a pixel defining layer, but not limited thereto. In some embodiments, when the electronic device  100  includes liquid crystal display (LCD), the second functional layer FL 2  may further include a common electrode, but not limited thereto. It should be noted that although the first functional layer FL 1  and the second functional layer FL 2  in  FIG. 1  are shown as a single layer respectively, the present disclosure is not limited thereto. In some embodiments, the first functional layer FL 1  and the second functional layer FL 2  may include multi-layer structure. 
     According to the present embodiment, as shown in  FIG. 2 , the electronic device  100  may for example be a border free device, that is, the electronic device  100  may not include the outer lead bonding region or the peripheral contact region of the electronic device  100  is located on the side-surface of the substrate (such as the first substrate SB 1 ), but not limited thereto. As shown in  FIG. 2 , the electronic device  100  may include a plurality of pixel areas PA and a plurality of wires WR, wherein the pixel areas PA and the wires WR may for example be located on the first substrate SB 1 , but not limited thereto. In the present embodiment, the pixel areas PA may for example be the areas of the electronic device  100  for displaying images, for example, each of the pixel areas PA may be a pixel or a sub-pixel of the electronic device  100 , but not limited thereto. The pixel areas PA may for example include the light emitting elements, the driving elements and/or the driving circuits mentioned above, but not limited thereto. The light emitting elements may be included in different pixel areas PA to emit lights of the same color or different colors (such as red light, green light and blue light, but not limited thereto). The light emitting elements for example may include light emitting diode (LED), organic light emitting diodes (OLED), mini light emitting diodes (mini LED), micro light emitting diodes (micro LED), other types of light emitting diodes or the combinations of the above-mentioned light emitting diodes, but not limited thereto. The driving elements and/or the driving circuits may include thin film transistor elements such as top gate thin film transistor, bottom gate thin film transistor, multi-gate thin film transistor or the combinations of the above-mentioned thin film transistors, but not limited thereto. In some embodiments, because the electronic device  100  may be a border free device, one or more the pixel areas PA may further include gate driver circuits (including shift registers and/or buffer), electrostatic discharge (ESD) protection elements (such as ESD diodes), inspection circuits, signal monitor lines and/or other suitable elements, but not limited thereto. The wires WR of the present embodiment may include any suitable signal line of the electronic device  100 . For example, the wires WR may include power lines of the light emitting elements, gate driver circuits, electrostatic discharge elements, data lines, scan lines, driver control signals, inspection lines and/or other suitable signal lines, but not limited thereto. The material of the wires WR may for example include copper, silver, gold, aluminum, other suitable conductive materials or the combinations of the above-mentioned materials, but not limited thereto. In some embodiments, the signal lines in the wires WR may be electrically connected to the elements in the pixel areas PA for signal transmission. For example, although the connection is not illustrated in  FIG. 2 , the data lines or scan lines in the wires WR may be electrically connected to the driving elements in the pixel areas PA to transmit driving signals, but not limited thereto. It should be noted that although  FIG. 2  only shows the wires WR extending along the direction X, the present disclosure is not limited thereto. The electronic device  100  may also include the wires WR extending along the direction Y, such as the scan lines, and the pixel areas PA may be defined as the regions formed by crossing of the data lines and the scan lines, but not limited thereto. The numbers, disposition positions and the shapes of each of the elements or the layers (such as the pixel areas PA and the wires WR) shown in  FIG. 2  are only for illustration, which can be adjusted according to the demands of the design. 
     As mentioned above, the electronic device  100  of the present disclosure may be a border free device. Therefore, a side printing process is needed to form the contacts between the wires WR and the peripheral circuits or connection pads (not shown), but not limited thereto. In the present embodiment, the peripheral circuits and/or connection pads may be disposed on the outer surface RS of the first substrate SB 1 , but not limited thereto. Therefore, as shown in  FIG. 1  and  FIG. 2 , the electronic device  100  of the present disclosure may include a plurality of first conductive wires CW 1  disposed on the first surface SF 1  and a plurality of dam walls DW disposed at the side of the electronic device  100 , and the side printing process may be performed on the electronic device  100  to form the contacts between the first conductive wires CW 1  and the peripheral circuits or connection pads (such as the process unit, but not limited thereto), such that the first conductive wires CW 1  may be electrically connected to the peripheral circuits or connection pads at the outer surface RS of the first substrate SB 1 . In some embodiments, as shown in  FIG. 1 , the dam walls DW may be disposed between the first functional layer FL 1  and the second functional layer FL 2 . The side printing process may be for example performed by using the metal paste to draw wirings on the side-surface of the substrate, wherein the metal paste may include any suitable metal material such as tin, silver(Ag), copper(Cu), gold(Au), palladium(Pb), platinum(Pt), etc., but not limited thereto. The description about the side printing process may be applied to each of the embodiments of the present disclosure, and will not be redundantly described in the following. In addition, it should be noted that although the first conductive wires CW 1  and the dam walls DW shown in  FIG. 2  are disposed at the lower side of the electronic device  100 , the present disclosure is not limited thereto. In some embodiments, the first conductive wires CW 1  and the dam walls DW may be disposed at one or more than one side of the electronic device  100 . 
     According to the present embodiment, the electronic device  100  includes a plurality of first conductive wires CW 1  and a plurality of dam walls DW disposed at the side of the electronic device  100 , but not limited thereto. In detail, as shown in  FIG. 1  and  FIG. 2 , the first conductive wires CW 1  and the dam walls DW are disposed on the first surface SF 1  of the first substrate SB 1 , but not limited thereto. The first side-surface SSF 1  and the second side-surface SSF 2  may be aligned to each other in the direction Z. In some embodiments, the functional layer (such as the first functional layer FL 1 ) may be disposed between the first conductive wires CW 1  and the first substrate SB 1  and/or the dam walls DW and the first substrate SB 1 , but not limited thereto. According to the present embodiment, as shown in  FIG. 1 , the dam walls DW may be located between any adjacent two of the first conductive wires CW 1  respectively, that is, the first conductive wires CW 1  and the dam walls DW are alternately disposed on the first surface SF 1 , such that the dam walls DW may separate any two adjacent first conductive wires CW 1 , but not limited thereto. For example, a first conductive wire CW 1 - 1  is disposed between a dam wall DW- 1  and a dam wall DW- 2 , and a first conductive wire CW 1 - 2  is disposed between the dam wall DW- 2  and a dam wall DW- 3 . In some embodiments, as shown in  FIG. 2 , the dam walls DW extend along the direction X, and the outer side-surface DWS of the dam walls DW may be substantially aligned with the first side-surface SSF 1 . The material of the first conductive wires CW 1  may refer to the material of the wires WR, and will not be redundantly described. Each of the dam walls DW of the present embodiment may include any suitable insulating materials, for example, the dam walls DW may include a pixel defining layer (PDL), color filter resin, silicone resin, epoxy resin, acrylic resin, other suitable insulating materials or the combinations of the above-mentioned materials, but not limited thereto. So that, the electronic device  100  may include the dam walls DW located between any adjacent two of the first conductive wires CW 1 , and the short of the first conductive wires CW 1  due to the abnormal conditions of the side printing process may be reduced, thereby improving the quality of the electronic device  100 . According to the present embodiment, the dam walls DW may be formed on the first surface SF 1  by photolithography, inkjet printing, screen printing, dispenser drawing or other suitable methods, but not limited thereto. 
     The details of the side printing process will be described in the following. In addition, according to the present embodiment, the thickness of the dam walls DW may be greater than the thickness of the first conductive wires CW 1 , but not limited thereto. In detail, as shown in  FIG. 1 , the first conductive wires CW 1  may have a thickness H 1  in the direction Z, the dam walls DW may have a thickness H 2  in the direction Z, and the thickness H 2  may be greater than the thickness H 1 , but not limited thereto. In some embodiments, as shown in  FIG. 1 , the thickness H 2  of the dam walls may for example be equal to the distance between the first functional layer FL 1  disposed on the first substrate SB 1  and the second functional layer FL 2  disposed on the second substrate SB 2 , that is, the dam walls DW may separate the first substrate SB 1  and the second substrate SB 2 , and the thickness H 1  of the first conductive wires CW 1  may be less than the thickness H 2 , but not limited thereto. It should be noted that the first functional layer FL 1  and the second functional layer FL 2  shown in  FIG. 1  are not limited to a single layer structure. For example, in some embodiments, the first functional layer FL 1  and the second functional layer FL 2  may include multi-layer structure respectively, and the distance between the first functional layer FL 1  and the second functional layer FL 2  may be defined as the distance between a surface of the first functional layer FL 1  and a surface of the second functional layer FL 2  which are the closest to each other, such as the distance between the surface FL 1 - 1  and the surface FL 2 - 1 , but not limited thereto. According to the present embodiment, the thickness H 2  of the dam walls DW greater than the thickness H 1  of the first conductive wires CW 1  may decrease the short situation of the first conductive wires CW 1  or decrease other unnecessary hurt to the first conductive wires CW 1  or the electronic device  100 , but not limited thereto. The relationship of the thicknesses of the first conductive wires CW 1  and the dam walls DW may be applied to each of the embodiments of the present disclosure, and will not be redundantly described in the following. 
     Referring to  FIG. 3A  and  FIG. 3B ,  FIG. 3A  schematically illustrates a partial top view of the first substrate of the electronic device in a side printing process according to the first embodiment of the present disclosure, and  FIG. 3B  schematically illustrates a partial side view of the electronic device in a side printing process according to the first embodiment of the present disclosure. In order to simplify the figure,  FIG. 3A  only shows a portion of the first substrate SB 1  of the electronic device  100 , and other elements of the electronic device  100  may refer to the above-mentioned contents, but not limited thereto. The structure shown in  FIG. 3A  may be the structure in the region RO shown in  FIG. 2 , but not limited thereto. As shown in  FIG. 3A  and  FIG. 3B , when the side printing process is performed on the electronic device  100 , according to some embodiments, the electronic device  100  may further include a plurality of second conductive wires CW 2  may be disposed corresponding to the first conductive wires CW 1  respectively, but not limited thereto. In detail, as shown in  FIG. 3B , during the side printing process, the second conductive wires CW 2  may be disposed on the first side-surface SSF 1  of the first substrate SB 1  and the second side-surface SSF 2  of the second substrate SB 2 , and the second conductive wires CW 2  may be electrically connected to the corresponding first conductive wires CW 1  respectively, for example, the first conductive wires CW 1  can be electrically connected to the peripheral circuits (such as the process unit) and/or connection pads through the second conductive wires CW 2 , but not limited thereto. In the present embodiment, the peripheral circuits and/or connection pads may for example be disposed on the outer surface RS of the first substrate SB 1 , but not limited thereto. In some embodiments, as shown in  FIG. 3A , the second conductive wires CW 2  may extend on the first surface SF 1  of the first substrate SB 1  and cover a portion of the first conductive wires CW 1 , thereby improving the electrical connection between the first conductive wires CW 1  and the second conductive wires CW 2 . That is, the portions of the second conductive wires CW 2  extending on the first surface SF 1  are disposed on the portions of the first conductive wires CW 1 . The material of the second conductive wires CW 2  may refer to the material of the first conductive material CW 1 , and will not be redundantly described here. 
     As mentioned above, when the side printing process is performed on the electronic device  100 , some abnormal conditions may occur, thereby causing a short of the first conductive wires CW 1  in the conventional technique. In detail, as shown in  FIG. 3A  and  FIG. 3B , the second conductive wires CW 21  shown in  FIG. 3A  represent the ideal second conductive wires CW 2  formed during the process without abnormal condition, wherein the second conductive wires CW 21  may substantially be aligned with the corresponding first conductive wires CW 1 , and the width of the second conductive wires CW 21  may be substantially the same as the width of the first conductive wires CW 1 , but not limited thereto. In some embodiments, the second conductive wire CW 2  with a width slightly less than the width of the first conductive wires CW 1  may also be the normal second conductive wire CW 21 , that is, a portion of the first conductive wire CW 1  may be exposed by the second conductive wire CW 21  in the side view shown in  FIG. 3B , but not limited thereto. The width mentioned above may for example be defined as the length along the direction Y, but not limited thereto. The definition of the normal second conductive wires CW 21  may be applied to each of the embodiments of the present disclosure, and will not be redundantly described in the following. Some abnormal conditions occurred in the side printing process are introduced in the following, but the present disclosure is not limited thereto. 
     In some embodiments, wider second conductive wires CW 2  may be occurred during the side printing process, which is one of the abnormal conditions mentioned above. Therefore, when the required resolution of the electronic device  100  is increased, the short of the first conductive wires CW 1  may be occurred due to the contact between adjacent two of the wider second conductive wires CW 2  in the conventional technique. In detail, as shown in  FIG. 3A  and  FIG. 3B , the wider second conductive wires CW 22  may be occurred during the side printing process, wherein the width of the second conductive wires CW 22  is excessively greater than the width of the first conductive wires CW 1 , such that the distance between the adjacent two second conductive wires CW 22  may be reduced, and the possibility of a short of the first conductive wires CW 1  may be increased. However, according to the present disclosure, because the electronic device  100  includes the dam walls DW disposed between any adjacent two of the first conductive wires CW 1 , the possibility of contact between the adjacent two second conducive wires CW 22  may be reduced, thereby reducing the short of the first conductive wires CW 1 . For example, it can be seen from  FIG. 3A  that the adjacent two second conductive wires CW 22  can be separated by the dam walls DW (such as the dam wall DW- 4 ) in a top view of the electronic device  100  even though they have a greater width, such that the possibility of short of the conductive wires (including the first conductive wires CW 1  and the second conductive wires CW 2 ) may be reduced, but not limited thereto. 
     In some embodiments, the shift of the second conductive wires CW 2  may be occurred during the side printing process, which is one of the abnormal conditions mentioned above. Therefore, the short of the first conductive wires CW 1  or the second conductive wires CW 2  may be occurred when the required resolution of the electronic device  100  is increased. In detail, as shown in  FIG. 3A  and  FIG. 3B , when the shift of the second conductive wires CW 2  is occurred, the second conductive wires CW 2  formed by the side printing process may be presented as the second conductive wires CW 23 , wherein the second conductive wires CW 23  are not aligned with the corresponding first conductive wires CW 1  and are at the right (or the left side) of the center lines CTL of the corresponding first conductive wires CW 1 , but not limited thereto. In such conditions, the possibility that the second conductive wire CW 23  is in contact with another first conductive wire CW 1  adjacent to the corresponding first conductive wire CW 1  of the second conductive wire CW 23  or in contact with another second conductive wire CW 2  adjacent to the second conductive wire CW 23  may be increased, and the possibility of a short of the first conductive wires CW 1  may be increased in a conventional display structure. However, according to the present disclosure, as shown in  FIG. 3A  and  FIG. 3B , because the electronic device  100  includes the dam walls DW disposed between adjacent two of the first conductive wires CW 1 , the shifted second conductive wires CW 23  would be blocked by the adjacent dam wall DW (such as the dam wall DW- 5 ) in the top view of the electronic device  100 , such that the contact between the second conductive wires CW 23  and other first conductive wires CW 1  or other second conductive wires CW 2  may be reduced, and the short of the first conductive wires CW 1  may thereby be reduced, but not limited thereto. 
     In some embodiments, when the side printing process is performed on the electronic device  100  with a small gap between the substrates (such as the first substrate SB 1  and the second substrate SB 2 ), a capillary phenomenon at the region between the first substrate SB 1  and the second substrate SB 2  may be occurred, which is one of the abnormal conditions mentioned above. Therefore, the short of the first conductive wires CW 1  may be occurred when the required resolution of the electronic device  100  is increased. In detail, as shown in  FIG. 3A  and  FIG. 3B , when the capillary phenomenon is occurred during the side printing process, the metal paste for forming the second conductive wires CW 2  may be pulled into the electronic device  100 , and the metal paste may fill the space between the first substrate SB 1  and the second substrate SB 2 . Accordingly, the second conductive wires CW 2  formed under this condition may represent as the second conductive wires CW 24  shown in  FIG. 3A  and  FIG. 3B , but not limited thereto. In such conditions, the distance between adjacent two of the second conductive wires CW 24  may be reduced, such that the possibility of contact between the second conductive wires CW 24  may be increased, and the possibility of short of the first conductive wires CW 1  may thereby be increased. However, according to the present disclosure, as shown in  FIG. 3A  and  FIG. 3B , because the electronic device  100  includes the dam walls DW disposed between any adjacent two of the first conductive wires CW 1 , the second conductive wires CW 24  can be separated by the dam walls DW (such as the dam wall DW- 6 ), such that the possibility of contact between the second conductive wires CW 24  may be reduced, and the short of the first conductive wires CW 1  may thereby be reduced, but not limited thereto. 
     As mentioned above, in the conventional technique, some abnormal conditions may occur during the side printing process, such that the conductive wires formed by the side printing process may be in contact, and the quality of the electronic device may be reduced. However, because the electronic device  100  of the present disclosure includes the dam walls DW, the second conductive wires CW 2  formed by the side printing process may be blocked by the dam walls DW even if the second conductive wires CW 2  are formed under the abnormal conditions. Therefore, the possibility of the short of the first conductive wires CW 1  may be reduced by the dam walls DW of the electronic device  100 . It should be noted that the shape and width of the dam walls DW shown in  FIG. 3A  and  FIG. 3B  are only illustrative, and the present embodiment is not limited thereto. In some embodiments, the width of each of the dam walls DW may be various and not be limited to the width of the dam walls DW shown in  FIG. 3A . For example, the width of each of the dam walls DW may be greater than a distance between two adjacent first conducive wires CW 1 , such that each of the dam walls DW may be partially overlapped with the corresponding first conductive wire CW 1  in the top view (direction Z) of the electronic device  100  (as shown in  FIG. 5 ). Therefore, the distance between two adjacent dam walls DW may be less than the width of the corresponding first conductive wire CW 1  or the corresponding second conductive wire CW 2 , but not limited thereto. 
     More embodiments of the present disclosure will be described in the following. In order to simplify the description, the same layers or elements in the following embodiments would be labeled with the same symbol, and the features thereof will not be redundantly described. The differences between each of the embodiments will be described in detail in the following contents. 
     Referring to  FIG. 4A  and  FIG. 4B ,  FIG. 4A  schematically illustrates a partial top view of the first substrate of an electronic device according to a second embodiment of the present disclosure, and  FIG. 4B  schematically illustrates a partial top view of the first substrate of the electronic device in a side printing process according to the second embodiment of the present disclosure. In order to simplify the figure,  FIG. 4A  and  FIG. 4B  only show a portion of the first substrate SB 1  of the electronic device  200 , and other elements of the electronic device  200  may refer to the electronic device  100  of the first embodiment, but not limited thereto. In addition, the structure shown in  FIG. 4A  and  FIG. 4B  may refer to the region RO shown in  FIG. 2 , but not limited thereto. One of the main differences between the electronic device  200  shown in  FIG. 4A  and  FIG. 4B  and the electronic device  100  shown in  FIG. 1  is the design of the dam walls DW. According to the present embodiment, the dam walls DW of the electronic device  200  may for example be patterned, and each of the patterned dam walls DW may be partially overlapped with the corresponding first conductive wire CW 1  in a top view direction, parallel to the direction Z, of the electronic device  100 , for example, each of the patterned dam wall DW may surround a portion of the corresponding first conductive wire CW 1 , but not limited thereto. In detail, as shown in  FIG. 4A  and  FIG. 4B , the manufacturing method of the dam walls DW of the present embodiment may for example include providing a preliminary substrate PSB including the first substrate SB 1  and a cutting portion CP, and a preliminary dam wall PDM may for example be formed on the preliminary substrate PSB by dispenser drawing, but not limited thereto. In some embodiments, the preliminary dam wall PDM may be formed by inkjet printing, screen printing, photolithography or other suitable methods. After the preliminary dam wall PDM is formed on the preliminary substrate PSB, a cutting process is performed to cut out the cutting portion CP of the preliminary substrate PSB, and the first substrate SB 1  of the electronic device  200  is remained, but not limited thereto. Therefore, when the cutting portion CP of the preliminary substrate PSB is cut out, a portion (such as the portion P 1 ) of the preliminary dam wall PDM may also be removed, and the dam walls DW of the present embodiment are thereby formed, but not limited thereto. According to the present embodiment, as shown in  FIG. 4A  and  FIG. 4B , the dam walls DW may for example be upside down U-shaped, and each of the dam walls DW may surround a portion of the corresponding first conductive wire CW 1  close to the first side-surface SSF 1  and be partially overlapped with the corresponding first conductive wire CW 1 , such that the portions of any adjacent two of the first conductive wires CW 1  near the first side-surface SSF 1  are separated by the patterned dam walls DW, but not limited thereto. In some embodiments, the dam walls DW may include any suitable shape as long as they can separate the first conductive wires CW 1 , the present disclosure is not limited thereto. As mentioned above, because the dam walls DW of the present embodiment may separate any adjacent two of the first conductive wires CW 1 , the possibility of a short of the first conductive wires CW 1  during the side printing process may be reduced even if some of the abnormal conditions are occurred in the side printing process. For example, as shown in  FIG. 4B , the second conductive wires CW 22  (wider conductive wires), the second conductive wires CW 23  (shifted conductive wires) and the second conductive wires CW 24  (affected by capillary phenomenon) are formed under different abnormal conditions of the side printing process mentioned above, while the second conductive wires CW 21  are formed ideally. The details of different conditions of the side printing process are not redundantly described here. It can be seen from  FIG. 4B  that the dam walls DW of the present embodiment may separate the second conductive wires CW 2  formed under different conditions of the side printing process, thereby preventing the second conductive wire CW 2  from being in contact with another second conductive wire CW 2 . Therefore, the possibility of the short of the first conductive wires CW 1  caused by the contact between the second conductive wires CW 2  may be reduced due to the dam walls DW of the present embodiment, and the quality of the electronic device may thereby be improved. The design of the dam walls DW of the present embodiment may be applied to each of the embodiments of the present disclosure. 
     Referring to  FIG. 5 ,  FIG. 5  schematically illustrates a partial top view of the first substrate of an electronic device in a side printing process according to a third embodiment of the present disclosure. In order to simplify the figure,  FIG. 5  only shows a portion of the first substrate SB 1  of the electronic device  300 , and other elements of the electronic device  300  may refer to the electronic device  100  of the first embodiment, but not limited thereto. In addition, the structure shown in  FIG. 5  may be the structure corresponding to the region RO shown in  FIG. 2 , but not limited thereto. One of the main differences between the electronic device  300  shown in  FIG. 5  and the electronic device  100  shown in  FIG. 1  is the design of the dam walls DW. According to the present embodiment, the dam walls DW of the present embodiment may be designed to have a pattern making a distance between adjacent two of the dam walls DW be less than the width of the second conductive wires CW 2 , but not limited thereto. In detail, as shown in  FIG. 5 , the dam wall pattern shown in  FIG. 5  may be formed of the dam walls DW and a dam bar DB extending along the direction Y and across the first conductive wires CW 1 , wherein the dam walls DW of the present embodiment may be for example connected through the dam bar DB, but not limited thereto. In addition, as shown in  FIG. 5 , each of the plurality of the dam walls DW is partially overlapped with the corresponding two of the plurality of first conductive wires CW 1  in a top view direction (direction Z) of the electronic device  300  in the present embodiment, but not limited thereto. The direction Y mentioned above may be substantially parallel to the extending direction of scan lines (not shown) of the electronic device  300 , but not limited to. In some embodiments, the dam bar DB may not be included in the electronic device  300 , and the dam walls DW are separated from each other. The material of the dam bar DB may refer to the material of the dam walls DW, and will not be redundantly described here. The dam bar DB and the dam walls DW may be formed together. Accordingly, the dam walls DW of the present embodiment may be regarded as the protruding portions protruded from the dam bar DB respectively, or in other words, the dam walls DW of the present disclosure are separated, and the first conductive wires CW 1  are included (or exposed) between any adjacent two of the dam walls DW; the dam bar DB of the present embodiment may be regarded as a continuous dam wall extending along the direction Y and across the first conductive wires CW 1 , and the first conductive wires CW 1  are not exposed by the dam bar DB, but not limited thereto. In the present embodiment, as shown in  FIG. 5 , a distance W 1  is included between any adjacent two of the dam walls DW, and the second conductive wires CW 2  formed in the side printing process may include a width W 2 , wherein the distance W 1  between adjacent two of the dam walls DW may be less than the width W 2  of the second conductive wires CW 2 , but not limited thereto. The feature that the distance W 1  between adjacent two of the dam walls DW is less than the width W 2  of each of the second conductive wires CW 2  may be applied to each of the embodiments of the present disclosure, and will not be redundantly described in the following. 
     According to the present embodiment, in order to improve the electrical connection between the first conductive wires CW 1  and the second conductive wires CW 2 , the contact area between the first conductive wires CW 1  and the second conductive wires CW 2  may be increased, wherein the contact area between the first conductive wires CW 1  and the second conductive wires CW 2  may be increased by pulling up the metal paste for forming the second conductive wires CW 2  during the manufacturing process of the electronic device  300 , but not limited thereto. In addition, as mentioned above, each of the plurality of dam walls DW is partially overlapped with the corresponding one of the plurality of first conductive wires CW 1  in a top view direction (direction Z) of the electronic device  300 , which may bring the advantage that the possibility of contact between the second conductive wires CW 2  and other adjacent first conductive wires CW 1  in the side printing process may be reduced, thereby reducing the possibility of short of the first conductive wires CW 1 . In detail, as shown in  FIG. 5 , before the side printing process of the electronic device  300 , a plate heating process may be performed to heat the plate (or the first substrate SB 1 , but not limited thereto). After that, the side printing process may be performed to dispose the metal paste on the side-surface (such as the first side-surface SSF 1  and the second side-surface SSF 2 ) in order to form the second conductive wires CW 2  (as shown in the portion P 2  of  FIG. 5 ). Because the temperature of the first substrate SB 1  is increased, the metal paste may expand, such as along the dam walls DW (for example, extend along the direction X) due to thermal expansion, thereby increasing the contact area between the first conductive wires CW 1  and the metal paste (second conductive wires CW 2 ). In addition, the manufacturing method of the second conductive wires CW 2  of the present disclosure may further include a cooling process after the plate heating process and the side printing process. In detail, it can be seen from  FIG. 5  that when the side printing process is performed to dispose the metal paste, a space (such as the space Si shown in the portion P 2 ) enclosed by the metal paste, the dam walls DW and the dam bar DB may be formed, and when the temperature of the electronic device  300  is reduced due to the cooling process, the pressure of the space Si enclosed by the metal paste, the dam walls DW and the dam bar DB may be reduced, such that the metal paste may be pulled into the electronic device  300  due to the pressure difference, and the contact area between the first conductive wires CW 1  and the metal paste may be increased. Moreover, as mentioned above, because the distance W 1  between adjacent two of the dam walls DW is less than the width W 2  of the second conductive wires CW 2  in the present embodiment, the metal paste for forming the second conductive wires CW 2  may extend into the electronic device  300  farther, such that the electrical connection between the first conductive wires CW 1  and the second conductive wires CW 2  may be improved, but not limited thereto. In another aspect, if the width W 2  of the second conductive wires CW 2  is less than the distance W 1  between the dam walls DW, the gas in the space Si may leak out, and the pulling effect caused by the gas may be reduced. Therefore, the design that the distance W 1  is less than the width W 2  may improve the pulling effect, but not limited thereto. The structure in which the metal paste is pulled may refer to the portion P 3  shown in  FIG. 5 . Accordingly, the portion P 3  shows the more likely structure of the electron device  300  of this embodiment. According to the present embodiment, because the first conductive wires CW 1  and/or the second conductive wires CW 2  are separated by the dam walls DW of the present embodiment, the short of the first conductive wires CW 1  caused by the contact between the second conductive wires CW 2  may be reduced even if the second conductive wires CW 2  are formed under the abnormal conditions of the side printing process mentioned above. The design of the dam walls DW of the present embodiment may be applied to each of the embodiments of the present disclosure, and will not be redundantly described in the following. 
     Referring to  FIG. 6 ,  FIG. 6  schematically illustrates a partial top view of the first substrate of an electronic device in a side printing process according to a fourth embodiment of the present disclosure. In order to simplify the figure,  FIG. 6  only shows a portion of the first substrate SB 1  of the electronic device  400 , and other elements of the electronic device  400  may refer to the electronic device  100  of the first embodiment, but not limited thereto. In addition, the structure shown in  FIG. 6  may be the structure corresponding to the region RO shown in  FIG. 2 , but not limited thereto. One of the main differences between the electronic device shown in  FIG. 6  and the electronic device shown in  FIG. 5  is the design of the dam walls DW. According to the present embodiment, as shown in  FIG. 6 , the dam bar DB and the dam walls DW of the electronic device  400  may be separated in the present embodiment, but not limited thereto. In addition, a gap GP may be formed between the dam bar DB and the dam walls DW, and two adjacent dam walls DW may be separate from each other to form a via VA in the present embodiment, but not limited thereto. The material of the dam bar DB may refer to the material of the dam walls DW, and will not be redundantly described here. As mentioned above, the electrical connection between the first conductive wires CW 1  and the second conductive wires CW 2  may be improved by increasing the contact area between the first conductive wires CW 1  and the second conductive wires CW 2 , and according to the present embodiment, because the gap GP is formed between the dam bar DB and the dam walls DW, the pulling of the metal paste for forming the second conductive wires CW 2  may for example be performed through the gap GP, but not limited thereto. In detail, as shown in  FIG. 6 , the vacuum equipment VE may for example be connected to two ends of the gap GP, and the side printing process is performed to dispose the metal paste on the side-surface (the first side-surface SSF 1  and the second side-surface SSF 2 ) of the electronic device  400 , as shown in the portion P 4  of  FIG. 6 . It should be noted that the side printing process and the connection between the vacuum equipment VE and the electronic device  400  may be performed in any suitable order, and the present disclosure is not limited thereto. After that, the vacuum equipment VE may be turned on, such that the gas in the space (such as the space S 3 ) formed by the dam walls DW and the metal paste may be removed by the vacuum equipment VE through the gap GP and the vias VA, but not limited thereto. The gas flow may for example be shown as the arrows AR of  FIG. 6 . Therefore, the metal paste disposed in the side printing process may be pulled into the electronic device  400  due to the pressure difference, and the contact area between the first conductive wires CW 1  and the metal paste (the second conductive wires CW 2 ) may be increased (as shown in the portion P 5  of  FIG. 6 ), thereby improving the electrical connection between the first conductive wires CW 1  and the second conductive wires CW 2 . The portion P 5  in  FIG. 6  may be considered as the structure of the electronic device  400  after the side printing process according to this embodiment. It should be noted that because the pulling process of the metal paste may be performed through the gap GP and the vacuum equipment VE in the present embodiment, the plate heating process may not be needed, and the manufacturing process may thereby be simplified, but not limited thereto. Similarly, because the distance W 1  between adjacent two of the dam walls DW is less than the width W 2  of the second conductive wires CW 2  in the present embodiment, the metal paste for forming the second conductive wires CW 2  may be pulled into the electronic device  400  farther, such that the electrical connection between the first conductive wires CW 1  and the second conductive wires CW 2  may further be improved, but not limited thereto. In addition, the design that the distance W 1  is less than the width W 2  may prevent the gas from leaking, thereby improving the pulling of the metal paste, but not limited thereto. In the present embodiment, as shown in  FIG. 6 , because the dam walls DW of the present embodiment may separate the first conductive wires CW 1  and/or the second conductive wires CW 2 , the short of the first conductive wires CW 1  caused by the contact between the second conductive wires CW 2  may be reduced even if the second conductive wires CW 2  are formed under the abnormal conditions of the side printing process mentioned above. The design of the dam walls DW of the present embodiment may be applied to each of the embodiments of the present disclosure, and will not be redundantly described in the following. 
     Referring to  FIG. 7A  and  FIG. 7B ,  FIG. 7A  schematically illustrates a partial top view of the first substrate of an electronic device according to a fifth embodiment of the present disclosure, and  FIG. 7B  schematically illustrates a partial side view of the electronic device according to the fifth embodiment of the present disclosure. In order to simplify the figure,  FIG. 7A  only shows a portion of the first substrate SB 1  and the color filters CF of the electronic device  500 , and other elements of the electronic device  500  may refer to the electronic device  100  of the first embodiment, but not limited thereto. In addition, the structure shown in  FIG. 7A  may be the structure corresponding to the region RO shown in  FIG. 2 , but not limited thereto. According to the present embodiment, as shown in  FIG. 7A  and  FIG. 7B , the electronic device  500  may include a color filter layer CFL disposed on the second substrate SB 2 . The color filter layer CFL may include a plurality of color filters CF, wherein the dam walls DW of the present embodiment may be disposed corresponding to the color filters CF respectively, but not limited thereto. In addition, the color filters CF of the present embodiment may not be overlapped with the first conductive wires CW 1  in the top view direction (such as the direction Z) of the electronic device  500 , but not limited thereto. It should be noted that although the electronic device  100  shown in  FIG. 1  does not show the color filters, the color filters thereof may be included in the second functional layer FL 2 , which is mentioned above. The color filters CF shown in  FIG. 7A  and  FIG. 7B  may for example be the color filters of the same color or different colors, and the present disclosure is not limited thereto. For example, the color filters CF shown in  FIG. 7A  and  FIG. 7B  may include the color filters of red, green and blue arranged alternately, but not limited thereto. According to the present embodiment, as mentioned above, because the material of the dam walls DW may include color filter resin, and the dam walls DW are disposed corresponding to the color filters CF, the dam walls DW and the color filters CF may for example be formed in the same step of the manufacturing process of the electronic device  500 , thereby simplify the process, but not limited thereto. In some embodiments, the dam walls DW of the present embodiment may include other suitable materials in addition to color filter resin. The design that the dam walls DW are disposed corresponding to the color filters CF can be applied to each of the embodiments of the present disclosure, and will not be redundantly described in the following. According to the present disclosure, a side printing process can be performed to form the second conductive wires (not shown, which can be referred to  FIG. 3A ,  FIG. 3B  and  FIG. 4B ) on the first side-surface SSF 1  of the first substrate SB 1  and the second side-surface SSF 2  of the second substrate SB 2 . Each second conductive wire will connect to the corresponding first conductive wire CW 1  and may fill into the space between the corresponding two adjacent dam walls DW to cover a portion of the corresponding first conductive wire CW 1 , which will not be detailed repeatedly, as well as the sixth embodiment shown in  FIG. 8A  and  FIG. 8B . It should be noted that “the second conductive wire may fill into the space between two adjacent dam walls DW” mentioned above may represent that the second conductive wire is filled into the space, or, the second conductive wire is at least partially filled into the space, the present disclosure is not limited thereto. 
     Referring to  FIG. 8A  and  FIG. 8B ,  FIG. 8A  schematically illustrates a partial top view of the first substrate of an electronic device according to a sixth embodiment of the present disclosure, and  FIG. 8B  schematically illustrates a partial side view of the electronic device according to the sixth embodiment of the present disclosure. In order to simplify the figure,  FIG. 8A  only shows a portion of the first substrate SB 1  and the color filters CF of the electronic device  600 , and other elements of the electronic device  600  may refer to the electronic device  100  of the first embodiment, but not limited thereto. In addition, the structure shown in  FIG. 8A  may be the structure corresponding to the region RO shown in  FIG. 2 , but not limited thereto. One of the main differences between the electronic device shown in  FIG. 8A  and  FIG. 8B  and the electronic device shown in  FIG. 7A  and  FIG. 7B  is the design of the color filters CF. According to the present embodiment, as shown in  FIG. 8A  and  FIG. 8B , the electronic device  600  may include a color filter layer including a plurality of color filters CF, wherein the dam walls DW of the present embodiment may be disposed corresponding to the color filters CF respectively. In addition, the color filters CF of the present embodiment may for example be connected to each other, that is, the color filters CF may at least be partially overlapped with the first conductive wires CW 1  in the top view direction (direction Z) of the electronic device  600 , and there is no gap between any adjacent two of the color filters CF, but not limited thereto. Therefore, the first conductive wires CW 1  of the present embodiment may for example be covered by the color filters CF, but not limited thereto. It should be noted that in the present disclosure, the term “a layer covers another layer” may be applicable to the condition that there is no other layer disposed between the layer and the another layer and to the condition that other layers may be disposed between the layer and the another layer. Therefore, “the first conductive wires CW 1  are covered by the color filters CF” mentioned above may include the conditions that there is no layer disposed between the first conductive wires CW 1  and the color filters CF, or other layers may be disposed between the first conductive wires CW 1  and the color filters CF, but not limited thereto. The types or colors of the color filters CF may be referred to in the above-mentioned contents, and will not be redundantly described here. According to the present embodiment, because there is no gap between the color filters CF of the electronic device  600 , some peripheral elements such as the bonding pad or conductive wires (for example, the first conductive wires CW 1 , but not limited thereto) may be shielded by the color filters CF, such that the peripheral elements may not be easily perceived by the users, thereby improving the performance of the electronic device  600  or the border free electronic device may be generated. The design of the color filters CF of the present embodiment may be applied to each of the embodiments of the present disclosure, and will not be redundantly described in the following. 
     Referring to  FIG. 9A  and  FIG. 9B ,  FIG. 9A  schematically illustrates a partial top view of the first substrate of an electronic device in a side printing process according to a seventh embodiment of the present disclosure, and  FIG. 9B  schematically illustrates a partial side view of the electronic device in a side printing process according to the seventh embodiment of the present disclosure. In order to simplify the figure,  FIG. 9A  only shows a portion of the first substrate SB 1  of the electronic device  700 , and other elements of the electronic device  700  may refer to the electronic device  100  of the first embodiment, but not limited thereto. In addition, the portion of the first substrate SB 1  shown in  FIG. 9A  may be the portion of the first substrate SB 1  corresponding to the region RO shown in  FIG. 2 , but not limited thereto. According to the present embodiment, as shown in  FIG. 9A  and  FIG. 9B , the electronic device  700  may include a first substrate SB 1 , a second substrate SB 2 , a plurality of first conductive wires CW 1  disposed on the first substrate and a plurality of first dam walls DW 1  disposed on the first substrate SB 1  and the second substrate SB 2 , but not limited thereto. In detail, as shown in  FIG. 9A  and  FIG. 9B , the first substrate SB 1  may include a first surface SF 1  and a first side-surface SSF 1  adjacent to the first surface, the second substrate SB 2  includes a second surface SF 2  and a second side-surface SSF 2  adjacent to the second surface SF 2 , the first conductive wires CW 1  are disposed on the first surface SF 1  of the first substrate SB 1 , and the first dam walls DW 1  are disposed on the first side-surface SSF 1  of the first substrate SB 1  and the second side-surface SSF 2  of the second substrate SB 2 , wherein the first dam walls DW 1  may be located between any adjacent two of the second conductive wires CW 2  respectively in the top view shown in  FIG. 9A , but not limited thereto. According to some embodiments, the first dam walls DW 1  may be located between any adjacent two of the first conductive wires CW 1  respectively in the top view shown in  FIG. 9A , but not limited thereto. The material of the first dam walls DW 1  may refer to the material of the dam walls mentioned in the embodiments above, but not limited thereto. The first dam walls DW 1  of the present embodiment may for example be disposed on the first side-surface SSF 1  and the second side-surface SSF 2  through inkjet printing, screen printing or dispenser drawing, but not limited thereto. In addition, as shown in  FIG. 9B , the electronic device  700  of the present embodiment may include a first functional layer FL 1  disposed on the first surface SF 1  and a second functional layer FL 2  disposed on the second surface SF 2 , but not limited thereto. The first substrate SB 1 , the second substrate SB 2 , the first conductive wires CW 1 , the first functional layer FL 1  and the second functional layer FL 2  of the present embodiment may refer to the above-mentioned embodiments, and will not be redundantly described here. According to the present embodiment, because the electronic device  700  includes the first dam walls DW 1  disposed on the first side-surface SSF 1  and the second side-surface SSF 2 , the conductive wires formed during the side printing process may be separated by the first dam walls DW 1 , that is, the contact between the conductive wires may be reduced by the first dam walls DW 1 , such that the short of the first conductive wires CW 1  may be reduced. In detail, as shown in  FIG. 9A  and  FIG. 9B , in the side printing process, a plurality of second conductive wires CW 2  may be disposed on the first side-surface SSF 1  of the first substrate SB 1  and the second side-surface SSF 2  of the second substrate SB 2  to be electrically connected to the corresponding first conductive wires CW 1  respectively, such that the first conductive wires CW 1  may be electrically connected to the peripheral circuits (such as the process unit) through the second conductive wires CW 2  after the second conductive wires CW 2  are electrically connected to the peripheral circuits, but not limited thereto. In the present embodiment, the peripheral circuits may for example be disposed on the outer surface RS of the first substrate SB 1 , but not limited thereto. As mentioned above, some abnormal conditions may be occurred during the side printing process, such that the possibility of contact between adjacent two of the second conductive wires CW 2  may be increased. For example, as shown in  FIG. 9B , the conductive wires formed under abnormal conditions such as the wider second conductive wires CW 22 , the shifted second conductive wires CW 23  and the second conductive wires CW 24  affected by capillary phenomenon may increase the possibility of short of the first conductive wires CW 1 . The details are mentioned above, and will not be redundantly described here. However, as shown in  FIG. 9B , because the first dam walls DW 1  of the present embodiment may block the second conducive wires CW 2  even if the second conductive wires CW 2  are formed under abnormal conditions, the possibility of contact between the second conductive wires CW 2  may be reduced, thereby reducing the short of the first conductive wires CW 1 , but not limited thereto. In addition, because the second conductive wires CW 2  may be blocked by the first dam walls DW 1 , as shown in  FIG. 9B , in the direction Y, the distance W 1  between adjacent two of the first dam walls DW 1  may be greater than the width of one of the second conductive wires CW 2  W 2 . The design of the first dam walls DW 1  of the present embodiment may be applied to each of the embodiments of the present disclosure, and will not be redundantly described in the following. 
     Referring to  FIG. 10A  and  FIG. 10B ,  FIG. 10A  schematically illustrates a partial top view of an electronic device in a side printing process according to an eighth embodiment of the present disclosure, and  FIG. 10B  schematically illustrates a partial side view of the electronic device in a side printing process according to the eighth embodiment of the present disclosure. In order to simplify the figure,  FIG. 10A  only shows a portion of the first substrate SB 1  of the electronic device  800 , and other elements of the electronic device  800  may refer to the electronic device  100  of the first embodiment, but not limited thereto. In addition, the portion of the first substrate SB 1  shown in  FIG. 10A  may be the portion of the first substrate SB 1  corresponding to the region RO shown in  FIG. 2 , but not limited thereto. One of the main differences between the electronic device  800  shown in  FIG. 10A  and  FIG. 10B  and the electronic device shown in  FIG. 9A  and  FIG. 9B  is the design of the dam walls. According to the present embodiment, as shown in  FIG. 10A , the electronic device  800  may further include a plurality of second dam walls DW 2  disposed on the first surface SF 1  of the first substrate SB 1  in addition to the first dam walls DW 1  mentioned above, but not limited thereto. That is, the electronic device  800  of the present embodiment may include the first dam walls DW 1  disposed on the first side-surface SSF 1  and the second side-surface SSF 2  and the second dam walls DW 2  disposed on the first surface SF 1 . The disposition and material of the first dam walls DW 1  and the second dam walls DW 2  of the present embodiment may refer to the dam walls DW of the embodiments mentioned above, and will not be redundantly described. In the present embodiment, as shown in  FIG. 10A , the first dam walls DW 1  and the second dam walls DW 2  are disposed between any adjacent two of the first conductive wires CW 1  in the top view of the electronic device  800 , and each of the first dam walls DW 1  may correspond to a corresponding second dam walls DW 2  or may be in contact with a corresponding second dam walls DW 2 , but not limited thereto. The first dam walls DW 1  and the second dam walls DW 2  may include the same material or include different materials in the present embodiment. Similarly, as mentioned above, because the electronic device  800  of the present embodiment includes the first dam walls DW 1  and the second dam walls DW 2 , the conductive wires (such as the second conductive wires CW 2 ) formed in the side printing process may be separated by the first dam walls DW 1  and the second dam walls DW 2  even if the conductive wires are formed under abnormal conditions (for example, the wider second conductive wires CW 22 , the shifted second conductive wires CW 23  and the second conductive wires CW 24  affected by the capillary phenomenon), such that the short of the first conductive wires CW 1  may be reduced, and the quality of the electronic device  800  may be improved. The design of the first dam walls DW 1  and the second dam walls DW 2  may be applied to each of the embodiments of the present disclosure. 
     Referring to  FIG. 11A  and  FIG. 11B ,  FIG. 11A  schematically illustrates a partial top view of an electronic device in a side printing process according to a ninth embodiment of the present disclosure, and  FIG. 11B  schematically illustrates a partial side view of the electronic device in a side printing process according to the ninth embodiment of the present disclosure. In order to simplify the figure,  FIG. 11A  only shows a portion of the first substrate SB 1  of the electronic device  900 , and other elements of the electronic device  900  may refer to the electronic device  100  of the first embodiment, but not limited thereto. In addition, the portion of the first substrate SB 1  shown in  FIG. 11A  may be the portion of the first substrate SB 1  corresponding to the region RO shown in  FIG. 2 , but not limited thereto. One of the main differences between the electronic device  900  shown in  FIG. 11A  and  FIG. 11B  and the electronic device shown in  FIG. 9A  and  FIG. 9B  is the design of the dam walls. 
     According to the present embodiment, as shown in  FIG. 11A  and  FIG. 11B , the electronic device  900  may further include a third dam wall DW 3  disposed on the first surface SF 1  of the first substrate SB 1 , wherein the third dam wall DW 3  may for example be filled between the first substrate SB 1  and the second substrate SB 2 , and the third dam wall DW 3  may cover at least a portion of the first conductive wires CW 1  close to the second conductive wires CW 2 , but not limited thereto. In detail, as shown in  FIG. 11A  and  FIG. 11B , the third dam wall DW 3  of the present embodiment may for example be a continuous layer covering the portion of the first conductive wires CW 1  close to the second conductive wires CW 2 , and the surfaces (such as the surface ES of the first conductive wire CW 1 ) of the first conductive wires CW 1  may be exposed by the third dam wall DW 3 , but not limited thereto. According to the present embodiment, the third dam wall DW 3  may be disposed between the first functional layer FL 1  and the second functional layer FL 2 . In the present embodiment, the material of the third dam wall DW 3  may be referred to in the material of the dam walls mentioned above, and will not be redundantly described here. The third dam wall DW 3  and the first dam walls DW 1  may include the same material or include different materials, the present disclosure is not limited thereto. According to the present embodiment, as mentioned above, because the electronic device  900  includes the first dam walls DW 1  and the third dam wall DW 3 , the conductive wires (such as the second conductive wires CW 2 ) formed in the side printing process may be separated by the first dam walls DW 1  and the third dam wall DW 3  even if the conductive wires are formed under abnormal conditions (for example, the wider second conductive wires CW 22 , the shifted second conductive wires CW 23  and the second conductive wires CW 24  affected by the capillary phenomenon shown in  FIG. 11B ), such that the short of the first conductive wires CW 1  may be reduced, and the quality of the electronic device  900  may be improved. It should be noted that in the side printing process of the present embodiment, the second conductive wires CW 2  may for example be in contact with the first conductive wires CW 1  through the surfaces (such as the surface ES shown in  FIG. 11A  and  FIG. 11B ) of the first conductive wires CW 1  exposed by the second dam wall DW 2 , but not limited thereto. In addition, as shown in  FIG. 11A  and  FIG. 11B , because the third dam wall DW 3  of the present embodiment is filled between the first substrate SB 1  and the second substrate SB 2 , such that moisture or oxygen may be blocked by the third dam wall DW 3 , the electronic elements disposed in the electronic device  900  may be protected by the third dam wall DW 3 , but not limited thereto. It should be noted that although the third dam wall DW 3  is filled into the first substrate SB 1  and the second substrate SB 2  and connects the first substrate SB 1  and the second substrate SB 2 , the present embodiment is not limited thereto. In some embodiments, the third dam wall DW 3  may be disposed on the first substrate SB 1  and covers the first conductive wires CW 1  without being in contact with the second substrate SB 2 , but not limited thereto. The design of the first dam wall DW 1  and the third dam wall DW 3  may be applied to each of the embodiments of the present disclosure. 
     In the present embodiment, the thickness of the first dam walls DW 1  may be greater than the thickness of the second conductive wires CW 2 , but not limited thereto. In detail, as shown in  FIG. 11A  and  FIG. 11B , the first dam walls DW 1  may have a thickness H 3 , and the second conductive wires CW 2  may have a thickness H 4 , wherein the thickness H 3  is greater than the thickness H 4 . It should be noted that the thickness of the second conductive wires CW 2  may be defined by using any one of the second conductive wires CW 2 , and the thickness H 4  shown in  FIG. 11A  is only an example. In addition, when the second conductive wires CW 2  includes irregular shape (such as the second conductive wires CW 24  shown in  FIG. 11A , but not limited thereto), the thickness of the second conductive wire may for example be the maximum thickness of the second conductive wire CW 2  in the direction Z (i.e. in a top view direction), but not limited thereto. According to the present disclosure, the electronic devices may be mass produced, wherein the metal paste for forming the second conductive wires of an electronic device and the metal paste for forming the second conductive wires of another electronic device adjacent to the electronic device may be in contact with each other, thereby reducing the yield. However, according to the present embodiment, because the thickness H 3  of the first dam wall DW 1  is greater than the thickness H 4  of the second conductive wires CW 2 , the possibility of contact between the second conductive wires CW 2  in different electronic devices may be reduced, thereby improving the yield. The design mentioned above may be applied to each of the embodiments of the present disclosure. 
     In summary, an electronic device is provided by the present disclosure, wherein the electronic device includes the dam walls disposed between any adjacent two of the conductive wires. Therefore, when the side printing process is performed on the electronic device to form the contacts between the conductive wires and the peripheral circuits, the short of the conductive wires may be reduced by the dam wall, thereby improving the quality of the electronic device. 
     Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the disclosure. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
