Abstract:
A liquid crystal display device comprises a poly-silicon TFT substrate having a condenser type digital analog converter, an another substrate disposed so as to face the poly-silicon TFT substrate, and liquid crystal positioned between the poly-silicon TFT substrate and the another substrate. In this liquid crystal device, a light blocking film is formed on a surface of the another substrate and contacts with the liquid crystal. The light blocking film has a resistance larger than n·τ/CLC wherein n is a number of bits of the condenser type digital analog converter, τ is an operation stabilizing time of a condenser per one bit, and CLC is electrostatic capacitance between the poly-silicon TFT substrate and the another substrate.
