Abstract

The present invention discloses a manufacturing method of a graphene electrode. In the manufacturing method of the present invention, a carbon source which is patterned is formed on the metal substrate with photoresist, or as metal layer which is patterned is formed on the carbon source. The metal substrate or metal layer after heating is used to catalyze the carbon source in direct contact therewith into graphene, and thus to form the graphene which is patterned to be used as a graphene electrode which is patterned in a display device. Apparently, the manufacturing method of the graphene electrode according to the present invention can simplify the manufacturing process and can reduce the difficulty of patterning the graphene electrode and the processing cost. The present invention further provides a liquid crystal display panel, comprising the graphene electrode manufactured by the foregoing method.
