Abstract

The invention is concerned with a kind of thin film transistor array, relating to base plate, many thin film transistors, many pixel poles, many wirings for sharing and many auxiliary electrode. The base plate has many pixel areas, while the thin film transistor, pixel pole and auxiliary electrode set in each pixel area respectively. Inside of each pixel area, pixel pole covers the wiring for sharing and connects with thin film transistor. Auxiliary electrode is between pixel poles and wiring for sharing, the overlap area of auxiliary electrode and wiring for sharing is L multiply with H and the sum of borders to overlap area is larger than 2L multiply with 2H. The L and H are both positive real numbers. The feedback pressure of each pixel area is equality to this thin film transistor array.

Description

technical field [0001] The present invention relates to a thin film transistor array (thin film transistor array, TFTarray), and in particular to a thin film transistor array capable of improving display brightness uniformity of a display. Background technique [0002] The thin film transistor liquid crystal display is mainly composed of a thin film transistor array, a color filter (color filter) and a liquid crystal layer (liquid crystal layer). FIG. 1 is a partial schematic diagram of an existing thin film transistor array. Please refer to FIG. 1 , the thin film transistor array 100 is mainly composed of a plurality of pixel structures 110 arranged in an array. Each pixel structure 110 is composed of a scan line 112 , a data line 114 , a TFT 116 and a pixel electrode 118 electrically connected to the TFT 116 . [0003] Please continue to refer to FIG. 1, the thin film transistor 116 is used as a switching element of the pixel structure 110, and the scan wiring 112 and th...
