Patent ID: 8873003

Claim:
A manufacture method of a liquid crystal display device, comprising the steps of: A. coating a black electrical conductive adhesive onto a color film substrate, and a shape of the coated black electrical conductive adhesive being corresponding to a predetermined shape of a black matrix; and B. curing the black electrical conductive adhesive to form the black matrix; the step A comprising the steps of: A1.adhering a mask plate on the color film substrate, and a pattern of the mask plate being the predetermined shape of the black matrix; A2. coating the black electrical conductive adhesive onto the mask plate; and A3. pre-curing the black electrical conductive adhesive and then removing the mask plate; the step B specifically comprising the steps of: B1. using a light having a wavelength of 100 to 400 nm to irradiate the black electrical conductive adhesive for 30 to 540 seconds; and B2. baking the black electrical conductive adhesive for 300 to 1200 seconds under the temperature of 50 to 200° C.; wherein the black electrical conductive adhesive includes an ultraviolet curing resin and doped grapheme particles, and the volume ratio of the doped grapheme particles in the black electrical conductive adhesive being in the range of 20 to 85%.
