Description

A liquid crystal display panel and a liquid crystal display device

technical field

The utility model relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a liquid crystal display device.

Background technique

In recent years, with the improvement of display technology, ultra-thin and ultra-narrow bezel display (Blade) has become a market development trend; the current main bottleneck of ultra-narrow bezel technology is the design of the panel periphery, and the optimized peripheral design is used to achieve the narrowest possible edge Effect.

As shown in FIG. 1 , in the prior art, a liquid crystal display panel includes: a color filter substrate 11 , a black matrix 15 disposed on the color filter substrate 11 , and a second pixel corresponding to the liquid crystal filling area disposed on the side of the color filter substrate 11 . An alignment layer 12; an array substrate 14, a second alignment layer 17 disposed on the side of the array substrate 14 corresponding to the liquid crystal filling region; a liquid crystal layer 13 located between the color filter substrate 11 and the array substrate 14, The liquid crystal layer 13 is located in the liquid crystal filling area; in the peripheral area of the liquid crystal display panel formed after the array substrate 14 and the color filter substrate 11 are boxed together, the liquid crystal layer 13 is located between the array substrate 14 and the color filter substrate 11. A sealant 16 is also coated between the substrates 11 .

However, in the manufacturing process of the above-mentioned display panel, the black matrix (BM) 15 around the liquid crystal display panel is made on the color filter (CF) substrate 11. When the box is aligned, the existing process is to carry out UV (ultraviolet) from the CF substrate. Irradiation, UV irradiation from CF will not be blocked, if there is BM around CF, it will block UV light and cannot be irradiated, so the existing process cannot be used. Instead, it is irradiated from the side of the array (Array) substrate, and the side of the Array substrate needs to be irradiated. When the display panel is turned over, LC (liquid crystal) drops on the color filter substrate to produce ODF Mura (One Drop Filling Mura, liquid crystal dripping filling spots); Holding (waiting) time increases, and at the same time, the misalignment and alignment accuracy of the substrate substrate deteriorates, which affects the contrast ;

In addition, the above-mentioned sealing glue (Seal glue) 16 is coated on the color filter substrate 11, and the surrounding black matrix 15 is made on the color filter substrate 11 to affect the sealing glue coating and dry width detection, thereby affecting mass production. At the same time, UV cannot be irradiated according to the side of the conventional color filter substrate, and the substrate substrate needs to be turned over, which affects the mass production time and the contrast of the alignment accuracy becomes worse;

Furthermore, on ultra-narrow or borderless liquid crystal display panel products, the black matrix covers the periphery of the panel. If BM material is not used on the periphery of the array substrate, other alternatives cannot be used to prevent light leakage around the periphery. For example, opaque metal can be used instead , but it will affect the metal wiring of the array substrate and the design of the array substrate or cause a short circuit problem.
