Abstract

A homeotropic alignment liquid crystal display panel with pixel region comprises a first substrate, a second substrate, a plurality of strip-shaped alignment bulges, a liquid crystal layer configured between the two substrates as well as a first polarizer and a second polarizer respectively arranged at the other side of the first substrate and the second substrate. At least part of the strip-shaped alignment bulges are positioned on the first substrate. A plurality of liquid crystal molecules are arranged in the liquid crystal layer and show diverse tilting directions by the corresponding strip-shaped alignment bulges. A first light penetrating axis of the first polarizer and a second light penetrating axis of the second polarizer are orthogonal. The strip-shaped alignment bulges are consistently folded strip-shaped bulges composed by a plurality of first alignment sections and a plurality of second alignment sections by alternatively connecting, the extending directions of the first alignment sections and the second alignment sections are in parallel with the first light penetrating axis and the second light penetrating axis. The invention can achieve the multi-range alignment wide viewing angle effect, can block light leakage and can increase the contrast ratio of the display image and show excellent effect.

Description

technical field

[0001] The present invention relates to a liquid crystal display panel, in particular to a vertical alignment liquid crystal display (VA-LCD) capable of improving light leakage and improving image contrast. Background technique

[0002] Existing liquid crystal display panels tend to develop towards high brightness, high contrast, large-area display and wide viewing angle. In order to overcome the viewing angle problem of large-sized liquid crystal display panels, the wide viewing angle technology of liquid crystal display panels must also be constantly improved and developed. breakthrough. Among them, Vertical Alignment Liquid Crystal Display (VA-LCD) is currently a relatively common liquid crystal display panel used in wide viewing angle technology.

[0003] For a general vertically aligned liquid crystal display panel, the protrusions or slits arranged on the color filter substrate or the active element array substrate can make the liquid crystal molecules...
