ABSTRACT:
A light-transmitting interlayer insulating film is provided over TFTs, gate signal lines and source signal lines. Pixel electrodes are provided on the interlayer insulating film, The signal lines and the pixel electrodes partially overlap each other via the interlayer insulating film which has such a low dielectric constant that substantially no capacitance is generated therein. Each pixel electrode is connected to a drain electrode of each TFT at the bottom of a contact hole passing through the depth of the interlayer insulating film. A light-blocking film is provided so as to partially overlap a periphery of a display area.
