Embodiment Construction

[0022] see Figure 4 , is a three-dimensional exploded schematic view of the first embodiment of the liquid crystal display panel of the present invention. The liquid crystal display panel 200 includes a first substrate 210 , a second substrate 220 opposite to the first substrate 210 , and a liquid crystal layer 230 sandwiched between the first substrate 210 and the second substrate 220 . The first substrate 210 includes a first alignment film 211 , a first compensation film 213 and a first polarizer 215 sequentially disposed along a direction away from the liquid crystal layer 230 . The second substrate 220 includes a second alignment film 221 , a second compensation film 223 and a second polarizer 225 sequentially disposed along a direction away from the liquid crystal layer 230 . The liquid crystal layer 230 includes a plurality of liquid crystal molecules (not shown).

[0023] The first compensation film 213 and the second compensation film 223 are both discotic liquid c...

Abstract

The invention relates to an LCD panel, which comprises a first substrate, a second substrate arranged relative to the first substrate, and a liquid crystal layer clamped between the first substrate and the second substrate, wherein the first substrate comprises a first compensation film; the second substrate comprises a second compensation film; the deviation of the two compensation films is phi, phi is not equal to 0; a horizontal shaft parallel to the LCD panel is defined; and an included angle of a compensation shaft of the first compensation film and the horizontal shaft is theta1, an included angle of a compensation shaft of the second compensation film and the horizontal shaft is theta2, a rotating angle of liquid crystal molecules of the liquid crystal layer is theta3, wherein theta1+theta2+theta3=180 degrees+phi'; phi' is a correction term; and phi' is more than 0 degree and less than 2phi.

Description

technical field [0001] The invention relates to a liquid crystal display panel. Background technique [0002] The liquid crystal in the liquid crystal display panel itself does not have luminescent properties, it uses an electric field to control the twisting of the liquid crystal molecules to realize the passage or non-passage of light, so as to achieve the purpose of display. Usually, the liquid crystal driving mode of the liquid crystal display panel is a twisted nematic mode, but its viewing angle range is relatively narrow, that is, there will be color distortion and gray scale inversion phenomenon when viewed at a large angle, and the display quality is poor. In order to increase the viewing angle of the twisted nematic liquid crystal display panel, a variety of wide viewing angle technologies have been proposed in the industry, among which, the use of a wide viewing angle compensation film (Wide View Film, WVF) is currently widely used as a wide viewing angle technolo...
