Abstract

The invention relates to a pixel structure and a method for manufacturing the same. The manufacture method comprises the following steps of providing a substrate; forming a thin film transistor, a first protection layer, a flat layer possessing a first opening, a patterned first conductive layer possessing a second opening, a second protection layer and a light resistance pattern layer on the substrate; via the light resistance pattern layer, etching the second protection layer to form a third opening exposed out of a part of the patterned first conductive layer and a part of the first protection layer; via the patterned first conductive layer, etching the first protection layer to form a fourth opening exposed out of a part of a drain electrode of the thin film transistor; removing the light resistance pattern layer; and forming patterned second conductive layers of the patterned first conductive layer and the drain electrode electrically connected in the second, third and fourth openings and on the second protection layer.

Description

Technical field [0001] The present invention relates to a pixel structure and a manufacturing method thereof, in particular to a high-resolution pixel structure and a manufacturing method thereof. Background technique [0002] Flat-panel displays, such as liquid crystal displays, have replaced traditional cathode ray tube (CRT) displays and have become the mainstream of displays due to their characteristics of lightness, thinness, short size, low radiation, and low power consumption. In the development of the display, it is constantly moving in the direction of high-resolution requirements. However, with the increase in resolution, the number of thin film transistors (TFT) on the panel has also increased, resulting in the continuous reduction of the available space on the panel. At the same time, in order to improve the aperture ratio and the performance of thin film transistors, the number of photo-etching processes (hereinafter referred to as PEP) has been increased in the pro...
