Abstract

The invention discloses an array substrate and a liquid crystal display. The array substrate comprises a lining substrate, data lines and grid lines are transversely and longitudinally intersected to form a plurality of pixel units and formed in a pixel area of the lining substrate, each pixel unit comprises a switch element, a pixel electrode and a public electrode, and the public electrode of each pixel unit is provided with a slit. The slit of the public electrode and / or pixel electrode of each pixel unit is in a shape of a fold line, the slits are mutually parallel to form a slit area, and the edge of a pixel electrode pattern is parallel to the edge of the slit area. The slit of the public electrode of each pixel unit is in the shape of the fold line, the edge of the pixel electrode pattern is parallel to the edge of the slit area, and each integral pixel unit is accordant to bending of a corresponding electric field in shape, so that the electric field in each pixel unit is uniform in distribution, displaying uniformity of the pixel units is improved, and aperture ratio and displaying contrast ratio are increased.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to an array substrate and a liquid crystal display. Background technique [0002] A liquid crystal display is a commonly used flat panel display at present, and a Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) is a mainstream product in the liquid crystal display. [0003] LCD can be divided into various types according to different forms of electric field, including Advanced-Super Dimensional Switching (AD-SDS), which generates parallel electric fields and The vertical electric field generated between the pixel electrode layer and the common electrode layer forms a multi-dimensional spatial compound electric field, which enables rotation conversion of all oriented liquid crystal molecules between the pixel electrodes and directly above the electrodes in the liquid crystal cell, thereby improving the working efficiency of the planar oriented liquid crystal and in...
