Liquid crystal display device and manufacture method thereof

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.
