Abstract

The invention provides a pixel structure, which comprises an active component, an upper pixel electrode and a lower pixel electrode. The upper pixel electrode is electrically connected with the active component and has a first crossed electrode and a plurality of upper alignment slit groups. The upper alignment slit groups are positioned in regions divided by the first crossed electrode, and define a plurality of alignment regions. A V-shaped main slit is formed between the upper pixel electrode and the lower pixel electrode, and has a tip end and two branches connected with the tip end, wherein the tip end faces the lower pixel electrode. The lower pixel electrode has a second crossed electrode and a plurality of lower alignment slit groups, and the lower alignment slit groups define a plurality of alignment regions, wherein one of the upper alignment slit groups adjacent to each branch is parallel to the adjacent branch, and one of the lower alignment slit groups adjacent to each branch is parallel to the adjacent branch.

Description

【Technical field】 [0001] The invention relates to a pixel structure and a liquid crystal display, in particular to a pixel structure and a liquid crystal display with good display quality. 【Background technique】 [0002] As the display specifications of liquid crystal displays continue to develop toward large sizes, the market's performance requirements for liquid crystal displays tend to be high contrast (High Contrast Ratio), fast response, and wide viewing angle. In order to overcome the viewing angle problem of large-size liquid crystal display panels, The wide viewing angle technology of the liquid crystal display panel must also continuously improve and break through. Among them, the multi-domain vertical alignment mode (MVA mode) liquid crystal display panel is currently a relatively common wide viewing angle technology, such as the multi-domain vertical alignment mode (Multi-domain vertical alignment, MVA) liquid crystal display panel, Polymer Stabilized Alignment (...
