Active matrix type liquid crystal device

Abstract

Abstract PURPOSE:To prevent the voltage of a picture element electrode from varying and a leak current from being generated by coating a drain bus line, a gate bus line, and a thin film transistor (TR) with a light-shielding conductive film across a protective insulating film, and connecting the conductive film to the gate bus line in precedent scanning order. CONSTITUTION:The light-shielding conductive film 7 is formed on the drain bus line 2, gate bus line 3, and thin film transistor (TFT) 4 which are formed on an insulating substrate like a glass substrate 1 across the protective insulating film 5. Further, this conductive film 7 is connected to the gate bus line 3 in precedent scanning order. Consequently, the voltage variation of the picture electrode 6 due to capacity coupling can be suppressed and the generation of a leak current due to the light of the TFT 4 is precluded, so operation characteristics are stabilized and fine voltage control for obtaining a sharp image is facilitated. Further, black stripes are arranged for respective picture elements, so the image becomes sharp.
