Liquid crystal display with back light and conductive diffuser
First Claim
1. A liquid crystal display with a back light for illuminating said liquid crystal display characterized by rendering electrically conductive a diffuser attached to a rear surface of said liquid crystal display which is mounted on a front surface opening of an electrically conductive casing for housing said back light, wherein said diffuser is rendered conductive by mixing a predetermined amount of conductive material into said diffuser in the manufacturing process of said diffuser, and further comprising an electrically conductive fitting means mounted on an inner surface of said electrically conductive casing and being in contact with said diffuser for making electrical continuity between said diffuser and said casing.
