Embodiment Construction

[0033] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 2 As shown, the present embodiment provides a liquid crystal panel, which includes an upper polarizer 1, an upper glass substrate 2, a color filter 3, a liquid crystal layer 5, a lower polarizer 6 and a lower glass substrate 8, the liquid crystal layer and A thin film transistor driving circuit layer 9 is arranged between the lower glass substrates, and an optical compensation film layer 7 is arranged between the color filter and the liquid crystal layer. The optical compensation film layer can improve the color shift by theoretically calculating the optimal retardation. Such as image 3 and Figure 4 As shown, in the liquid crystal panel without the optical compensation film layer, there is a large color shift problem; and the liquid crystal panel provided in this embodiment, whether it is an ADS (Advan...

Abstract

The invention relates to the technical field of liquid crystal display (LCD), in particular to a liquid crystal display panel and a liquid crystal display device. The liquid crystal display panel comprises a color filter and a liquid crystal layer, wherein an optical compensation film layer is arranged between the color filter and the liquid crystal layer. According to the liquid crystal display panel and the liquid crystal display device, the inside of the liquid crystal display panel is in a structure of the optical compensation film layer, so that an effect of increasing a contrast ratio can be exerted in an all-sight direction, and the structure has a function of improving color cast in an opposite angle direction of the liquid crystal display panel; the color filter of the liquid crystal display panel is coated with the optical compensation film layer, so that the liquid crystal display panel is compact in structure, the production cost is lowered, and light leakage and mura due to light reflection and refraction can be reduced; and the adopted optical compensation film layer can improve a gray level, the contrast ratio, a hue and the like of the LCD.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal panel and a liquid crystal display device. Background technique [0002] With the continuous development of LCD (Liquid Crystal Display, liquid crystal display) display technology, people's requirements for LCD quality are also constantly increasing. More and more liquid crystal panels whose viewing angles reach the level of wide viewing angle panels are favored by people. [0003] In the prior art, the liquid crystal panel using ADS or IPS technology has the problem of color shift in both diagonal directions. As attached in the manual figure 1 Provided in is an existing liquid crystal display, including an upper polarizer 1 , an upper glass substrate 2 , a color filter 3 , a protective film layer 4 , a liquid crystal layer 5 , a lower polarizer 6 and a lower glass substrate 8 . The upper polarizer 1 includes a triacetate cellulose TAC film 10 o...
