Liquid crystal display device.

摘要

An active matrix liquid crystal display device is disclosed, which has a plurality of display electrodes (15) arranged in a matrix array and selectable through control of thin film transistors (16) for application of voltage between selected display electrodes (15) and a common electrode to obtain image display. Each thin film transistor (16) has a semiconductor layer (21) and a gate insulating film (22) both formed to have the same pattern. Each thin film transistor (16) has a gate electrode (23) formed on the gate insulating film (22) with the edges of the gate electrode (23) inwardly spaced apart from the corresponding edges of the gate insulating film (22). The semiconductor layer (21) and gate insulating film (22) preferably have extensions extending under a corresponding gate bus.
