Problems solved by technology

[0005] In the existing technology, PVD, CVD and other technologies are mainly used to make ITO thin films. Although these technologies are relatively mature, the production cost is relatively high.
At the same time, the metal indium in ITO is a rare metal. With the continuous consumption and rising price, the application of ITO in industry is limited.
In addition, when making ITO special pattern electrodes, due to high resolution requirements, positive photoresist coating is also required, and the price of positive photoresist is high, resulting in increased manufacturing process costs

Abstract

The invention provides a patterned electrode manufacturing method, a liquid crystal display panel and a liquid crystal display panel manufacturing method. The patterned electrode manufacturing method comprises the steps of 1, mixing a graphene aqueous solution with a PEDOT:PSS solution according to a certain proportion to obtain a graphene / PEDOT:PSS mixed solution; 2, mixing the graphene / PEDOT:PSS mixed solution with photoresist according to a certain proportion and conducting stirring to obtain graphene / PEDOT:PSS photoresist with conductivity; 3, providing a substrate, applying the graphene / PEDOT:PSS photoresist prepared in the step 2 onto the substrate, and conducting exposure, development and baking to obtain a patterned electrode. Compared with traditional ITO electrode manufacturing methods, the patterned electrode manufacturing method has the advantages that the patterned electrode manufacturing processes can be simplified, and patterned electrode manufacturing cost can be reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a patterned electrode, a liquid crystal display panel and a method for manufacturing the same. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) is one of the most widely used flat panel displays at present, and a liquid crystal display panel is a core component of the liquid crystal display. A liquid crystal display panel is usually composed of a color filter substrate (ColorFilter, CF), a thin film transistor array substrate (ThinFilmTransistorArraySubstrate, TFTArraySubstrate), and a liquid crystal layer (LiquidCrystalLayer) disposed between the two substrates. Generally, pixel electrodes and common electrodes are respectively arranged on the array substrate and the color filter substrate. When a voltage is applied to the pixel electrode and the common electrode, an electric field will be generated in the liquid c...
