Abstract

The present invention provides a liquid crystal display device which can obviate cutting off of a peripheral region of the liquid crystal display device which is provided with an inspection circuit and can surely perform the inspection of an image display even when the peripheral region is narrowed. On a substrate of the liquid crystal display device, a pixel region which is comprised of a plurality of gate lines and a plurality of drain lines and a peripheral region which surrounds the pixel region are formed. A turn-on inspection terminal of the liquid crystal display device are formed on the peripheral region and a semiconductor chip for driving liquid crystal is formed on the inspection terminal. The semiconductor chip is electrically insulated from the inspection terminal.
