Benefits of technology

This design effectively prevents abnormal image display and light leakage, enhancing the display quality and allowing for a narrower frame while maintaining the performance of the color filter substrate.

Problems solved by technology

A black matrix layer in a display device is charged, so that the display device may display abnormally, which is a significant problem in the liquid crystal display product, and in the related art, this problem has been alleviated from the perspectives of its design in that the black matrix layer in the display device is designed with a non-straight edge, where the edge of the black matrix layer is designed in segments.
However a shorter distance between the black matrix layer and an Active Area (AA) of the display device is required for the advanced display device, so the existing demand fails to be satisfied by the original design, and the black matrix layer still tends to be charged so that an image tends to be displayed abnormally in the active area, thus seriously degrading the quality of the product.
Moreover when a backlight source operates with the black matrix layer with the non-straight edge designed in segments, light tends to be leaked at the edge of the display device; and the black matrix layer tends to be coupled with a part of GOA CLK signal lines so that the display device may display poorly.
