PROTECTIVE CIRCUIT OF SUBSTRATE FOR DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent uneven display when power is supplied to a protective circuit in a waiting mode. SOLUTION: Characteristic variation of a leak current of each transistor is suppressed by composing the protective circuit with the transistor of one and the same channel. By adjusting a channel width ratio of each transistor, a potential of a signal line S is controlled to the potential causing no visible display unevenness. COPYRIGHT: (C)2005,JPO&NCIPI
