Abstract
A process of fabricating a liquid crystal electro-optical (display) device. The device includes discharge accelerating patterns extending from associated gate bus patterns and provided with a unique geometry. The disclosed geometry minimizes the dielectric breakdown of a gate insulating film attributable to plasma discharge between gate and source/drain electrodes of the associated thin film transistors.
