▎ 摘　　要

NOVELTY - Preparing graphene electrode comprises e.g. providing a support plate, and forming a graphene layer on the support plate, providing a substrate, and covering the substrate on the graphene layer; using the substrate subjecting to laser irradiation corresponding to a desired pattern area of the graphene layer, and the desired pattern area of the graphene layer is adsorbed on the substrate, cooling the substrate, adhering the substrate laser irradiated portion to the graphene by adsorption; and separating the support plate from the substrate, and then separating the substrate. USE - The method is useful for preparing graphene electrode (claimed). DETAILED DESCRIPTION - Preparing graphene electrode comprises providing a support plate, and forming a graphene layer on the support plate, providing a substrate, and covering the substrate on the graphene layer; using the substrate subjecting to laser irradiation corresponding to a desired pattern area of the graphene layer, and the desired pattern area of the graphene layer is adsorbed on the substrate, cooling the substrate, adhering the substrate laser irradiated portion to the graphene by adsorption; and separating the support plate from the substrate, and then separating the graphene adhered to the substrate from the substrate thus to forming the graphene electrode patterned on the substrate. An INDEPENDENT CLAIM is also included for liquid crystal display panel comprising above mentioned graphene electrode and is prepared by above mentioned method.
