The pasting type polarization light with the built-in dye has the advantages of high polarization degree and good reliability.
However, after the stretched polarizing film is attached to the inner side of the substrate, shrinkage is likely to occur in a subsequent thermal process, especially at an edge with unbalanced stress, when the adhesive film and the polarizing film have good adhesion and deformation matching, the edge of the display panel is wrinkled, and when the matching is not good, the edge of the display panel is severely warped, and air bubbles appear in the middle of the warped portion. Even under the condition of optimal matching, wrinkles can also appear on the edge of the display panel, and the wrinkles can contact with an opposite substrate (array substrate), because transparent conductive films (ITO) are distributed on the opposite substrate, and the whole transparent conductive films are also distributed on the substrate (color film substrate) on the side of the built-in polarizing film, when the wrinkles contact with the opposite substrate, the ITO of the substrates on the two sides are conducted, and when the ITO of the substrates on the two sides is conducted, a potential difference which enables liquid crystals to deflect cannot be formed, and the display panel cannot display.
Therefore, it is necessary to provide a liquid crystal display panel and a liquid crystal display device to solve the problems of the prior art.

In the present invention, directional terms such as "up", "down", "front", "back", "left", "right", "inner", "outer", "side", etc. refer to directions of the attached drawings. Accordingly, the directional terms used are used for explanation and understanding of the present invention, and are not used for limiting the present invention. In the drawings, elements having similar structures are denoted by the same reference numerals.
As shown in fig. 1, the conventional liquid crystal display panel includes a color filter substrate 20, an array substrate 10, and a liquid crystal layer 30 disposed between the color filter substrate 20 and the array substrate 10.
The array substrate 10 includes a second substrate 11, and a second dye polarization film 12, a switch array layer 13 and a second transparent conductive layer 14 sequentially disposed on the second substrate 11.
The color film substrate 20 includes a first substrate 21, and a first dye polarizing film 22, a color resistance layer 23, and a first transparent conductive layer 24 'sequentially disposed under the first substrate 21, the sealant 25' is disposed under the first transparent conductive layer 24 ', and the first transparent conductive layer 24' completely covers the first substrate 21.
Referring to fig. 2 to 4, fig. 2 is a schematic structural diagram of a liquid crystal display device according to a first embodiment of the invention.
The liquid crystal display device of the embodiment includes a liquid crystal display panel, and the liquid crystal display panel includes a color film substrate 20, an array substrate 10, and a liquid crystal layer 30 disposed between the color film substrate 20 and the array substrate 10. Wherein the liquid crystal display panel has a display area.
The array substrate 10 includes a second substrate 11, and a second dye polarization film 12, a switch array layer 13 and a second transparent conductive layer 14 sequentially disposed on the second substrate 11.
The color film substrate 20 includes a first substrate 21, a first dye polarizing film 22, a color resist layer 23, a first transparent conductive layer 24, and a sealant 25, wherein the first dye polarizing film 22, the color resist layer 23, the first transparent conductive layer 24 are sequentially located under the first substrate 21, the sealant 25 is disposed under the color resist layer 23, the sealant 25 surrounds the outer side of the periphery of the display area, and in an embodiment, the sealant 25 is a closed rectangular frame.
The first transparent conductive layer 24 is disposed under an inner portion of the color resist layer 23, where the inner portion corresponds to a region inside the sealant 25. With reference to fig. 3 and 4, the dashed boxes in fig. 4 indicate that the outer periphery of the sealant 25, that is, the inner portion, is located at a position corresponding to the position of the region defined by the inner periphery 251 of the sealant 25. In a top view, the first transparent conductive layer 24 only partially covers the first substrate 21, and the first transparent conductive layer 24 corresponds to a position of a region defined by the inner edge 251 of the sealant 25. That is, the first transparent conductive layer 24 is not disposed under the first substrate 21 at the position corresponding to the sealant 25 and the position corresponding to the outer side of the sealant 25.
The first transparent conductive layer 24 is obtained by patterning the entire transparent conductive layer disposed under the first dye polarizing film. The patterning process may be one of exposure and development, inkjet printing, and the like. The mask used in the patterning process of the first transparent conductive layer 24 may be the same as the mask used for manufacturing the sealant.
The material of the first transparent conductive layer 24 is indium tin oxide.
In this embodiment, the first transparent conductive layer corresponding to the sealant and the first transparent conductive layer except the sealant are removed, so that the transparent conductive layers of the upper and lower substrates are prevented from being conducted when the edge of the display panel is wrinkled.
It is to be understood that the array substrate side in the present embodiment may also be provided with no second dye polarizing film 12, but with a polarizer below the second substrate 11.
Referring to fig. 5 to 7, fig. 5 is a schematic structural diagram of a liquid crystal display device according to a second embodiment of the invention.
The difference between this embodiment and the previous embodiment is that the first transparent conductive layer 24 in this embodiment is further disposed below an outer portion of the color resist layer 23, where the outer portion corresponds to a position of an outer region of the sealant 25.
With reference to fig. 6 and 7, wherein a dashed frame in fig. 7 indicates an outer periphery of the sealant 25, the first transparent conductive layer 24 includes a first portion 241 and a second portion 242, the first portion 241 corresponds to a position of an inner region of the sealant 25, and the second portion 242 corresponds to a position of an outer region of the sealant 25. The region inside the sealant 25 is defined by the inner periphery 251 of the sealant 25. The outer region of the sealant 25 is defined by the outer periphery 252 of the sealant 25. That is, the first transparent conductive layer 24 is not disposed under the color resist layer 23 corresponding to the position of the sealant 25. The shape of the gap between the first portion 241 and the second portion 242 is the same as the shape of the sealant 25.
It can be seen that the first transparent conductive layer 24 of the present embodiment forms two separated portions inside and outside the sealant 25, which can effectively prevent the transparent conductive layers of the upper and lower substrates corresponding to the display area from being conducted when the edge of the display panel is wrinkled.
The mask used in the patterning process of the first transparent conductive layer 24 in this embodiment may be the same as or different from the mask used for manufacturing the sealant.
Because the display panel adopts the structure of the built-in polarizing film, the thickness of the display panel can be reduced, and when the temperature in the environment is higher, the built-in polarizing film is not easy to warp, and simultaneously, the dye polarizer is more resistant to high temperature than the traditional iodine polarizer and is not easy to lose efficacy due to high temperature; in addition, the section of the polarizing film is protected in the frame glue, so that the polarizing effect of the polarizing film can be prevented from being influenced by moisture absorption.
It is understood that, returning to fig. 2 or 4, the liquid crystal display device of the present invention further includes a light guide plate 40 disposed on a side of the array substrate 10 away from the liquid crystal layer 30, and a backlight 50 disposed on a left side of the light guide plate 40. Of course, the backlight 50 may be disposed on the right side of the light guide plate 40.
According to the liquid crystal display panel and the liquid crystal display device, the first transparent conducting layer is arranged below the inner side part of the first dye polarizing film, so that the problem that the display panel cannot display due to conduction of the transparent conducting layers of the upper substrate and the lower substrate when the edge of the display panel is wrinkled is solved.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
