Active element matrix substrate

Abstract

The invention discloses to an active element matrix substrate. The substrate comprises a first patterning conductor layer, a dielectric layer, a second patterning conductor layer, a protective layer and a plurality of pixel electrodes, wherein the first patterning conductor layer comprises a plurality of scanning lines and common lines, a plurality of grid electrodes and a strip floating shading pattern; the dielectric layer covers the first patterning conductor layer and is provided with a plurality of contact openings which expose the common lines respectively; the second patterning conductor layer comprises a plurality of data wires, a plurality of source electrodes and drain electrodes, and a plurality of strip capacitance electrodes; each strip capacitance electrode is in electrical connection with one common line through one first contact opening; a clearance is reserved between each data wire and one strip capacitance electrode; each strip floating shading pattern is positionedbelow the data wire, the clearance and the strip capacitance electrode; and the pixel electrodes are in electrical connection with the drain electrodes through second contact openings of the protective layer.

Description

technical field [0001] The present invention relates to a substrate, and in particular to an active element matrix substrate. Background technique [0002] Among many Flat Panel Displays (FPDs), Liquid Crystal Displays (LCDs) have become the mainstream in the current market because of their superior characteristics such as high space utilization efficiency, low power consumption, no radiation, and low electromagnetic interference. [0003] Figure 1A It is a three-dimensional schematic diagram of a liquid crystal display in the prior art. Please refer to Figure 1A The liquid crystal display 100 has an active element matrix substrate 110 , an opposite substrate 120 , a liquid crystal layer 130 interposed between the active element matrix substrate 110 and the opposite substrate 120 , and a backlight module 140 for providing light. The active device matrix substrate 110 has a plurality of pixel units 112 and a plurality of signal lines 114 between the pixel units 112 , and t...
