First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing an advanced super dimension switch (ADS) liquid crystal display device, comprising steps as follows: disposing a first substrate and a second substrate opposite to each other; attaching a first polarizing sheet onto the first substrate; and attaching a second polarizing sheet onto the second substrate; wherein a graphene film is provided within the second polarizing sheet, the method further comprising a step as follows: connecting the graphene film a ground dotting area in a pad region on the first substrate by Ag paste or an electrically-conductive adhesive tape, wherein the second polarizing sheet comprises in sequence: an adhesive layer, a first supporting protective layer, a polarizer layer, a second supporting protective layer, and a surface-treatment layer, and wherein the first substrate is an array substrate and the second substrate is a color filter substrate, and the step that a graphene film is provided within the second polarizing sheet comprises: during preparing the second polarizing sheet, coating graphene-containing suspension or slurry on any one of the adhesive layer, the first supporting protective layer, the polarizer layer and the second supporting protective layer, then drying the suspension or slurry to obtain a graphene film, and then preparing the remaining layer of the second polarizing sheet on the graphene film. 2. The method according to claim 1 , wherein the second polarizing sheet is directly attached to a surface of the color filter substrate facing away from the array substrate.
