Problems solved by technology

Studies have shown that there is a light transmission phenomenon between the pixel electrode and the data line in this technical solution, which restricts the improvement of the aperture ratio to a certain extent. The liquid crystal is driven by the multi-dimensional space composite electric field, and the other part of the area is driven by the transverse electric field mode (In-Plane Switching, also known as in-plane switching).

Abstract

An array substrate comprises gate lines and data lines for defining pixel regions. A thin film transistor, a common electrode, and a pixel electrode with strip electrodes are formed in each pixel region, the common electrode is formed on a second insulating layer which covers the data line, the pixel electrode is formed on a third insulating layer which covers the common electrode. Thus, the area of the display region can be increased, and aperture ratio can be effectively improved.

Description

technical field [0001] The invention relates to a thin film transistor liquid crystal display and a manufacturing method thereof, in particular to a thin film transistor liquid crystal display array substrate and a manufacturing method thereof. Background technique [0002] In Thin Film Transistor Liquid Crystal Display (TFT-LCD) products, Advanced-Super Dimensional Switching (Advanced-Super Dimensional Switching; AD-SDS) is a technology that has emerged in recent years and can improve LCD picture quality. One of the most advanced technologies, it can achieve high penetration and large viewing angle requirements at the same time. AD-SDS technology forms a multi-dimensional space composite electric field through the parallel electric field generated by the edge of the pixel electrode in the same plane and the vertical electric field generated between the pixel electrode layer and the common electrode layer, so that the pixel electrodes in the liquid crystal cell, directly abo...
