Title: Thin film transistor matrix
Inventor: ICHIMURA TERUHIKO
IPC: G02F1/1368
Filed: 1987-02-19
Abstract: PURPOSE:To prevent voltage fluctuation of picture element electrodes by the potential of a drain bus line by forming a conductive film via a protective insulating film on the drain bus line. CONSTITUTION:Since the scanning sequence of the conductive film 7 is connected to a gate bus line 3' of the previous position, the potential VC thereof is kept at the low potential equal to the potential VG-1 of the gate bus line 3' of the previous position when a corresponding gate electrode is selected. The conductive film 7, therefore, acts as a sealing film between the picture element electrode 5 and the drain bus line 2 and the capacity CDS between both is lost of the capacity component CDS1 between the front faces out of the two capacity components and is only the capacity component CDS2 between the rear faces. The size of these two capacity components is larger with CDS1 the capacity component of which is about 3 times the capacity component of CDS2 and, therefore, the capacity CDS between the picture element electrode 5 and the drain bus line 2 is extremely small. The influence of the potential VD of the line 2 on the potential VLC of the picture element electrode 5 is consequently extremely lessened, by which the undesirable voltage fluctuation is suppressed and the good image quality is obtd.
