PROBLEM TO BE SOLVED: To obtain the liquid crystal display device which has visibility even in a dark place by forming an ITO film of an electrode film of an observer-side electrode plate and constituting an electrode film of a back electrode plate by sandwiching a silver allow thin film with specific thickness between transparent oxide films. SOLUTION: The observer-side electrode plate 2 and back electrode plate 3 are arranged opposite each other, and a liquid crystal material 40 is charged between both the electrode plates. The observer-side electrode plate 2 consists of a reflection preventive film 83 which is arranged on the observer-side top surface of a transparent substrate 70, a scatter film 60 arranged on the other surface, and an ITO film 50 which is arranged as an electrode on the scatter film 60 and drives liquid crystal and an oriented film. Further, the back electrode plate 3 consists of a light-reflective and light-transmissive electrode film 30 of three-layered constitution, which is arranged as an electrode on the observer-side surface of the back transparent substrate 20 and has a silver alloy thin film of 12 to 70nm in film thickness for driving the liquid crystal sandwiched between a lower transparent oxide thin film and an upper transparent oxide thin film, and an oriented film. |
