     TFT-LCD includes four processes: an array process, a color film process, a cell forming process, and a module process. The cell forming process includes manufacture procedures such as oriented film engineering, frame adhesive coating, liquid crystal instillation, vacuum cell pasting and cutting. The adhesive coating aims to connect the color film substrate and the array substrate to prevent liquid crystal from leaking and to maintain the thickness of the peripheral cell. 
     Before use, the frame adhesive is subjected to defoaming treatment to prevent small air bubbles in the frame adhesive, avoid that the small air bubbles affect the strength of the frame adhesive and guarantee that no broken line appears in the coating process. The frame adhesive coating guarantees the viscosity of the frame adhesive, stability of the coating amount, stability of the coating position and compatibility of liquid crystal. The main ingredient of the frame adhesive is a resin added with an additive, e.g., a thermally cured single crystal resin and a phenol resin, an epoxy resin that realizes cross linking under ultraviolet radiation. According to the type of the additive, the frame adhesive is divided into a thermally curing type and an ultraviolet curing type. The thermally curing type has a high strength and a long curing time. The ultraviolet curing type has a fast curing speed but a low strength. Currently, it is common in the TFT-LCD industry to add both the thermally curing resin and the ultraviolet curing resin. Ultraviolet curing is carried out immediately after opposite disposing pairing of the array substrate and the color film substrate. The ultraviolet curing mainly includes fast curing the periphery of the frame adhesive, so that it will not cause any error even when in contact with liquid crystal. Thermal curing is carried out after ultraviolet curing to strengthen the adhesion force of the frame adhesive. 
     As shown in  FIGS. 1 and 2 , after the vacuum pasting process, curing of the frame is carried out; if the array substrate (first substrate  120 ) side is selected to be radiated by the ultraviolet light to carry out ultraviolet curing on the frame adhesive  150 . In an area coated with the frame adhesive, the opaque layer on the array substrate side is a hollow design so as to enable the ultraviolet light to pass through conveniently. 
     As shown in  FIG. 3 , while coating with the frame adhesive  150 , in order to guarantee end-to-end connection, there are generally an overlapped area (first coating area  151 ) coated with the frame adhesive at the ends. In the overlapped area, the hollow area  122  of the array substrate does not satisfy the demand of ultraviolet curing of the frame adhesive by the ultraviolet radiation. 
     The present application is illustrated below in detail in reference with the drawings and optional embodiments. 
     As shown in  FIGS. 4 to 6 , in one or more embodiments of the present application, it discloses a display panel  110  including a display area  111  and a peripheral area  112 ; the display panel  110  includes: a first substrate  120 ; a second substrate  130  disposed in opposite to with the first substrate; and a frame adhesive  150  formed on the peripheral area  112  to adhere the first substrate  120  and the second substrate  130  in a sealing manner; the first substrate  120  includes a light shield layer  121 ; the light shield layer  121  is provided with a hollow area  122  formed on the peripheral area  112 ; the hollow area  122  is disposed corresponding to the frame adhesive  150 ; the hollow area  122  at least includes a first hollow area  123  and a second hollow area  124 ; and a width of the first hollow area  123  is greater than that of the second hollow area  124 . Specifically, the first substrate  120  is an array substrate, and the second substrate  130  is a color film substrate. 
     The first substrate  120  and the second substrate  130  are adhered through the frame adhesive  150  in a sealing manner; the main ingredient of the frame adhesive  150  is a resin added with an epoxy resin that realizes cross linking under ultraviolet radiation; and ultraviolet curing is carried out on the frame adhesive  150  immediately after opposite disposing of the first substrate  120  and the second substrate  130 . If ultraviolet light radiates from the first substrate  120  to carry out ultraviolet curing to the frame adhesive  150 , on one hand, the first substrate  120  is provided with a light shield layer  150  that shields the frame adhesive  150 , so that the ultraviolet light does not radiate the frame adhesive  150 , and it is difficult to cure the frame adhesive  150 ; on the other hand, in the coating process of the frame adhesive  150 , in order to guarantee seal adhering between the first substrate  120  and the second substrate  130 , a section of frame adhesive  150  is generally overlapped at the end part coated with the frame adhesive  150 , to completely connect the ends of the frame adhesive  150 ; the overlapped section of frame adhesive  150  is laminated to have a width greater than that of the non-overlapped frame adhesive  152 ; the widened frame adhesive  150  is shielded by the light shield layer  121 , the curing is affected, and the poor curing effect of the frame adhesive  150  will directly affect the adhesion force between the frame adhesive  150  and the first substrate  120  and the second substrate  130 , thereby affecting sealing between the first substrate  120  and the second substrate  130 . 
     In this scheme, the light shield layer  121  is provided with a first hollow area  123  and a second hollow area  124  corresponding to the coating area of the frame adhesive  150 , and a width of the first hollow area  123  is greater than that of the second hollow area  124 ; on one hand, the ultraviolet light that radiates from the first substrate  120  side can radiate the frame adhesive  150  or wider frame adhesive  150  through the hollow area  122  of the light shield layer  120 , so as to guarantee the curing effect of all the frame adhesive between the first substrate  120  and the second substrate  130 ; on the other hand, the frame adhesive  150  is laminated during opposite disposing of the first substrate  120  and the second substrate  130 ; and the frame adhesive  150  will fill the hollow area  122  of the light shield layer  121 , which increases contact area of the frame adhesive  150  and the light shield layer  121  of the hollow area  122  and strengthens the adhesion force between the frame adhesive  150  and the first substrate  120 . 
     In one or more embodiments, the coating area of the frame adhesive  150  at least includes a first coating area  151  and a second coating area  152 ; a width of the first coating area  151  is greater than that of the second coating area  152 ; and the first hollow area  123  corresponds to the first coating area  151 , and the second hollow area  124  corresponds to the second coating area  152 . 
     In this scheme, the first coating area  151  is the coating area where the frame adhesive  150  is overlapped, the second coating area  152  is the coating area where the frame adhesive  150  is not overlapped, and thus the width of the first coating area  151  is greater than that of the second coating area  152 . In order to guarantee that the widened first coating area  151  and second coating area  152  can be completely radiated by the ultraviolet light, the hollow area  122  is set correspondingly, so that the first hollow area  123  corresponds to the first coating area  151 , the second hollow area  124  corresponds to the second coating area  152 , and the width of the first hollow area  123  is greater than that of the second hollow area, thereby guaranteeing the curing effect of all the frame adhesive  150 . 
     In one or more embodiments, orthographic projection of the hollow area  122  on the first substrate  120  completely covers orthographic projection of the frame adhesive  150  on the first substrate  120 , and the orthographic projection area of the hollow area  122  is greater than the orthographic projection area of the frame adhesive  150 . The orthographic projection of the hollow area  122  on the first substrate  120  completely covers the orthographic projection of the frame adhesive  150  on the first substrate  120 , and the orthographic projection area of the hollow area  122  is greater than the orthographic projection area of the frame adhesive  150 , so that it guarantees that the frame adhesive  150  is completely located in the hollow area  122 ; and when the ultraviolet light radiates the hollow area  122  from the first substrate  120 , it can guarantee that the frame adhesive  150  is radiated sufficiently by the ultraviolet light, and the frame adhesive  150  has fast curing and a better effect. 
     In one or more embodiments, the width of the first hollow area  123  is greater than that of the first coating area  151 , and the width of the second hollow area  124  is greater than that of the second coating area  152 . 
     In this scheme, the width of the first hollow area  123  is greater than that of the first coating area  151 , so that it guarantees that the frame adhesive  150  of the first coating area  151  can be radiated by the ultraviolet light, so as to fast cure the edge of the frame adhesive  150  of the first coating area  151 ; and the second hollow area  124  is greater than that of the second coating area, so that it guarantees that the adhesive frame  150  of the second coating area  152  can be radiated by the ultraviolet light to fast cure the edge of the frame adhesive  150  of the second coating area  152 . 
     A distance between a border of the first hollow area  123  and a border of the first coating area  151  is the first distance, a distance between a border of the second hollow area  124  and a border of the second coating area  152 , and the first distance is equal to the second distance within a preset error precision. 
     Distances between borders of the first hollow area  123  and the second hollow area  124  and borders of the first coating area  151  and the second coating area  152  are the first distance and the second distance, respectively, so that the structure of the hollow area  122  is regular, and the preset interval shape of the frame adhesive  150  is regular, which is convenient for the light shield layer  121  to use an opening design of the mask while forming the hollow area  124  and is convenient to coat the frame adhesive  150 , thereby improving the manufacture efficiency of the display panel  110 . 
     Specifically, as shown in  FIG. 6 , two or more first hollow areas can be provided to facilitate coating of the frame adhesive  150  in different positions. 
     As another embodiment of the present application, referring to  FIGS. 8 and 9 , the difference from the above embodiments is that, an edge of the orthographic projection of the first hollow area  123  on the first substrate  120  is not in contact with an edge of the orthographic projection of the first coating area  151  on the first substrate  120 ; and an edge of the orthographic projection of the second hollow area  124  on the first substrate  120  is not in contact with an edge of the orthographic projection of the second coating area  152  on the first substrate  120 . 
     In this scheme, the edge of the orthographic projection of the first coating area  151  is not in contact with the first hollow area  123 , and the edge of the orthographic projection of the second coating area  152  is not in contact with the edge of the second hollow area  124 , so that it guarantees that the frame adhesive  150  is coated in the middle position of the hollow area  122  instead of the edge position of the hollow area  122 , avoids that the edge of the frame adhesive  150  cannot be radiated by the ultraviolet light, and affects curing of the edge of the frame adhesive  150 . 
     As another embodiment of the present application, the difference from the above embodiments is that, the width of the first hollow area  123  is greater than the sum of the width of the first coating area  151 , a coating error value and a cell pairing error value, a length of the first hollow area  123  is greater than the sum of a length of the first coating area  151 , the coating error value and the cell pairing error value, and the width of the second hollow area  124  is greater than the sum of the width of the second coating area  152 , the coating error value and the cell pairing error value. 
     In this scheme, there is a certain error value while coating the frame adhesive  150 , so that the coated frame adhesive  150  deviates from the predetermined frame adhesive  150  area; there is a certain error value during opposite disposing of the first substrate  120  and the second substrate  130 , so that offset occurs to correspondence between the hollow area  122  and the frame adhesive  150  area; and a part of the frame adhesive  150  cannot be radiated by the ultraviolet light during ultraviolet curing of the frame adhesive  150 , which affects the ultraviolet curing effect of the frame adhesive  150 . In this scheme, taking the above factors into full consideration, while designing the width of the hollow area  122 , the width of the hollow area  122  is greater than the sum of the width of the first coating area  151 , a coating error value and a cell pairing error value, a length of the first hollow area  123  is greater than the sum of a length of the first coating area  151 , the coating error value and the cell pairing error value, and the width of the second hollow area  124  is greater than the sum of the width of the second coating area  152 , the coating error value and the cell pairing error value, so that the frame adhesive  150  can be completely located in the hollow area  122  in a case in which the coating error value and the cell pairing error value present, and the frame adhesive  150  can be completely radiated by the ultraviolet light from the hollow area  122  during ultraviolet curing, thereby guaranteeing the ultraviolet curing effect of the frame adhesive  150 . 
     As another embodiment of the present application, referring to  FIGS. 7 to 9 , the first substrate  120  is an array substrate provided with a pixel electrode, and the light shield layer  121  is a hollow metal line; the second substrate  130  is provided with a first light shield layer  131  in a position corresponding to the frame adhesive  150 , and the first light shield layer  131  is formed of a black color resistance. 
     In this scheme, after the metal line of the first substrate  120  is provided with a hollow area  122  in the position of the frame adhesive  150 , if the corresponding second substrate  130  is provided with a first light shield layer  131 , the hollow area  122  leaks light and the display effect is affected; the hollow metal line on the first substrate  120  can allow the ultraviolet light that cures the frame adhesive  150  to pass through, so as to cure the frame adhesive  50 ; the black color resistance on the second substrate  130  can shield the hollow area  122  on the first substrate  120 , and shield the area on the second substrate  130  that may leak light, without additionally disposing a first light shield layer  131  in the position of the hollow area  122 , thereby removing the manufacture procedure of the first light shield layer  131  corresponding to the hollow area  122 . 
     Of course, the first substrate  120  may also be a color film substrate, the light shield layer  121  is a hollow black color resistance; correspondingly, the second substrate  130  is an array substrate, and the first light shield layer  131  is a metal line. 
     As another embodiment of the present application, referring to  FIGS. 10 and 11 , the difference from the above embodiments is that, it discloses a display panel  110  formed with a display area  111  and a peripheral area  112 ; the display panel  110  includes: an array substrate  141 ; a color film substrate  140  disposed opposite with the array substrate  141 ; and a frame adhesive  150  formed on the peripheral area  112  to adhere the first substrate  120  and the second substrate  130  in a sealing manner; 
     The array substrate  141  is provided with a metal line in a position corresponding to the peripheral area  111 ; the metal line includes a first hollow area  123  and a second hollow area  124 ; the first hollow area  123  and the second hollow area  124  are connected to form a rectangular closed-loop structure; the width of the first hollow area  123  is greater than that of the second hollow area  124 ; and the color film substrate  140  is provided with a black color resistance in a position corresponding to the first hollow area  123  and the second hollow area  124 ; 
     The frame adhesive  150  includes a first coating area  151  and a second coating area  152 ; the first coating area  151  and the second coating area  152  are connected to form a rectangular closed-loop structure; and the width of the first coating area  151  is greater than that of the second coating area  152 ; 
     The first hollow area  123  of the array substrate  141  corresponds to the first coating area  151 ; the orthographic projection of the first hollow area  123  on the first substrate  120  completely covers the orthographic projection of the first coating area  151  on the first substrate  120 ; and the edge of the orthographic projection of the first hollow area  123  on the first substrate  120  is not in contact with the edge of the orthographic projection of the first coating area  151  on the first substrate  120 ; 
     The second hollow area  124  of the array substrate  141  corresponds to the second coating area  152 ; the orthographic projection of the second hollow area  124  on the first substrate  120  completely covers the orthographic projection of the second coating area  152  on the first substrate  120 ; and the edge of the orthographic projection of the second hollow area  124  on the first substrate  120  is not in contact with the edge of the orthographic projection of the second coating area  152  on the first substrate  120 .
