Problems solved by technology

In the current liquid crystal display, the pixel structure contains many patterned film layers. For example, after forming the active elements in the pixel structure, it is often necessary to have another process to form the pixel electrode and the common electrode, which leads to the pixel structure complicated process

Abstract

A pixel structure includes a substrate, a first metal layer, a first insulating layer, a conductive layer, a second insulating layer and a second metal layer. The first metal layer is on the substrate. The first metal layer includes a data line and a source electrode connected to the data line. The first insulating layer covers the first metal layer. The conductive layer is on the first insulatinglayer. The conductive layer includes a semiconductor channel and a first electrode. The semiconductor channel is electrically connected to the source electrode. The first electrode is at least partially located in an open region of the pixel structure. The second insulating layer covers the conductive layer. The second metal layer is on the second insulating layer. The second metal layer includesa scan line and a grid electrode connected to the scan line. The gate overlaps the semiconductor channel.

Description

technical field [0001] The present invention relates to a pixel structure, and in particular to a pixel structure in which data lines are formed before semiconductor channels. Background technique [0002] Liquid crystal display is a kind of display with the most mature technology and the most widely used mode among many flat panel display devices. Generally speaking, a liquid crystal display includes a plurality of pixel structures, and the electrodes of the pixel structures are used to control the direction of liquid crystal molecules. Whether the light emitted by the backlight module can pass through the liquid crystal layer is controlled by the direction of the liquid crystal. In the current liquid crystal display, the pixel structure contains many patterned film layers. For example, after forming the active elements in the pixel structure, it is often necessary to have another process to form the pixel electrode and the common electrode, which leads to the pixel struct...
