Problems solved by technology

However, for Method 1, the cost of replacing the exposure machine for black ceramics is very high, with an average cost of about 3.1 million RMB per unit. However, the improvement effect of Method 2 is not obvious, and the cost is too high. Method 3 Non-reflective electrostatic fluid is harmful to the human body and is easy to corrode the exposure machine

Abstract

The invention provides a method for manufacturing a liquid crystal display apparatus. The method comprises steps of forming transistor elements and pixel electrodes on a glass substrate, sequentially forming a conductive layer, a metal layer and a light resistance layer on the transistor elements, exposing and developing the light resistance layer, firstly etching the metal layer, etching the conductive layer, peeling the light resistance layer, and secondly etching the metal layer to remove the metal layer. In the method for manufacturing the liquid crystal display apparatus, a metal layer is added on the conductive layer, light cannot emit to an exposure machine bench through a transparent conductive layer during exposure, mura, caused by reflection of the exposure machine bench, on an array substrate can be avoided, and the process is simple and the cost is low.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for manufacturing a liquid crystal display device. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as thinness, energy saving, and no radiation, so it has gradually replaced the traditional cathode ray tube (CRT) display. Currently, liquid crystal displays are widely used in high-definition digital televisions, desktop computers, personal digital assistants (PDAs), notebook computers, mobile phones, digital cameras and other electronic devices. [0003] Common liquid crystal displays can be divided into narrow viewing angle twisted nematic (Twisted Nematic, TN) LCD, super twisted nematic (Super Twisted Nematic, STN) LCD, double layer super twisted nematic (Double layer Super Twisted Nematic, DSTN) LCD and wide viewing angle fringe field switching technology (Fringe Field Switching, FFS) LCD, in...
