Array substrate

Abstract

An array substrate comprises a substrate body and a plurality of pixel units positioned on the substrate body, each pixel unit comprises a main pixel electrode, a sub-pixel electrode and a deep-and-shallow hole unit. Each of the deep-and-shallow hole units is used for lowering electrode potential of the sub-pixel electrode and comprises thin film stacking layers and floating conduction layers on the thin film stacking layers, the thin film stacking layer are provided with deep holes and shallow holes, openings are formed in positions, corresponding to junctions of the deep holes and the shallow holes, of the floating conduction layers, and protruding portions are arranged on two sides of the positions, corresponding to the junctions of the deep holes and the shallow holes, of the floating conduction layers. The array substrate has the advantages that stability in signal transmission among the deep holes and the shallow holes is guaranteed, and aligning abnormalities in a high perpendicular aligning process are reduced.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to an array substrate. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) is currently a display device that performs well in terms of brightness, contrast, power consumption, life, volume and weight. It has excellent performance and large-scale With good production characteristics, high degree of automation and broad development space, it has gradually occupied a dominant position in the display field. TFT-LCD is composed of thin film transistor array substrate (array substrate), color filter array substrate (CF substrate) and liquid crystal sandwiched between the two substrates. [0003] In order to meet the requirements of low color shift in the current liquid crystal display panel, the charge of the sub pixel electrode is introduced into the array common line (Arraycom line) by adding a third TFT switch and deep and shallo...
