Problems solved by technology

Since the biaxial compensation film has an in-plane compensation value Ro and an out-of-plane compensation value Rth in the thickness direction, the variation of the slow axis of the compensation film will cause a change in the polarization state of the incident light, thereby affecting the brightness of the outgoing light, causing light leakage in the dark state, and affecting the contrast.

Abstract

The invention relates to a liquid crystal display panel and a liquid crystal display. The liquid crystal display panel includes a first polarizing layer and a second polarizing layer which are disposed opposite to each other, a vertical alignment liquid crystal box disposed between the first polarizing layer and the second polarizing layer, and a double-optical axis compensation film. According tothe liquid crystal display panel and the liquid crystal display, the double-optical axis compensation film is used to compensate for the leakage of side view light, so that the contrast of the side view of the liquid crystal panel is maintained, the thickness of a polarizer is reduced, and at the same time, the effect of reducing warping during the preparation of the liquid crystal panel is achieved.

Description

technical field [0001] The present application relates to the field of liquid crystal display technology, in particular to a liquid crystal display panel and a liquid crystal display. Background technique [0002] A vertical alignment cell (VA cell) is a liquid crystal cell structure commonly used in displays, and refers to a display mode in which liquid crystal molecules are aligned vertically to a substrate. The vertical alignment display mode has become a display mode commonly used in large-sized liquid crystal panels due to its advantages of wide viewing angle, high contrast ratio, and no need for rubbing alignment. [0003] see figure 1 , figure 1 It is a schematic diagram of a specific structure of a double-layer biaxial (Biaxial) compensation film for a vertical alignment mode in the prior art. The liquid crystal panel in the vertical alignment display mode includes a first protective layer 121, a first polarizing layer 122, a first dual-axis compensation film 123,...
