Abstract

The invention discloses a double-layer double-shaft compensation structure for an LCD panel. The double-layer double-shaft compensation structure for the LCD panel comprises a first polarizing film, a first double-shaft compensation film, the LCD panel, a second double-shaft compensation film and a second polarizing film which are sequentially laminated. The LCD panel is provided with a liquid crystal layer comprising a plurality of liquid crystal molecules, the anisotropy of the refractive index of the liquid crystal layer is delta n, the thickness of the liquid crystal layer is d, and the pretilt angle of the liquid crystal molecules is theta. The compensation value inside the face of the first double-shaft compensation film is Ro1, the compensation value of the thickness of the first double-shaft compensation film is Rth1, the compensation value inside the face of the second polarizing film is Ro2, the compensation value of the thickness of the second polarizing film is Rth2, wherein 287.3 nm<=delta n*d<=305.7 nm; 85 degrees<=theta<90 degrees; 8 nm<=Ro1<=98 nm; 19 nm<=Rth1<=224 nm; 8.4 nm<=Ro2<=98 nm; Y1 nm<=Rth2<=Y2 nm; Y1=0.003115*(Rth1)2-1.6791*Rth1+231.67; Y2=-0.002225*(Rth1)2-0.37474*Rth1+241.7. The invention further discloses an LCD device which comprises the LCD panel in which the double-layer double-shaft compensation structure is used for compensating.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a double-layer biaxial compensation structure for a liquid crystal panel and a liquid crystal display device. Background technique [0002] Liquid Crystal Display (LCD) is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays have low power consumption, high image quality, small size, and light weight, so they are favored by everyone and become the mainstream of displays. Currently, liquid crystal displays are mainly thin film transistor (ThinFilm Transistor, TFT) liquid crystal displays. [0003] As the area of ​​TFT-LCD becomes larger and larger, the viewing angle increases, the contrast of the screen decreases, and the clarity of the screen decreases. This is the result of the birefringence of the liquid crystal molecules in ...
