    Abstract: A display device includes a display region, a peripheral region around the display region, a sealing portion provided in the peripheral region to seal a liquid crystal layer, and a liquid crystal supply portion provided at a part of the sealing portion and interconnecting an outside of the sealing portion and the display region. The peripheral region includes a first peripheral region which is provided between the display region and the sealing portion and from which an insulating film is removed and a second peripheral region which is provided between the display region and the sealing portion and in which the insulating film covering a circuit is formed. A light blocking film arranged so as to straddle the first and second peripheral regions and extending linearly in an extending direction of a boundary between the first and second peripheral regions is formed on a substrate.
