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.

Abstract: According to an aspect, a display device includes: an array substrate having a display region provided with a plurality of signal lines arranged with spaces in a first direction and a plurality of scanning lines arranged with spaces in a second direction; a counter substrate; a liquid crystal layer between the array substrate and the counter substrate; and a light source disposed so as to cause light to enter a side surface of the array substrate or a side surface of the counter substrate. The counter substrate is provided with a light-blocking layer. In a plan view, the light-blocking layer overlaps either of the signal lines and the scanning lines, and the other of the signal lines and the scanning lines each have a non-overlapping portion that does not overlap the light-blocking layer.

Abstract: A display device according to an aspect includes: an array substrate including a plurality of first light-transmitting electrodes each disposed in a corresponding one of pixels; a counter substrate including positions that overlap the first light-transmitting electrodes in a plan view and are provided with a second light-transmitting electrode; a liquid crystal layer including polymer-dispersed liquid crystals filled between the array substrate and the counter substrate; and at least one light emitter configured to emit light toward a side surface of the counter substrate. The array substrate includes, in each of the pixels, a third light-transmitting electrode and a conductive metal layer. The third light-transmitting electrode at least partially overlaps the first light-transmitting electrode in the plan view with an inorganic insulating layer interposed therebetween, and the conductive metal layer is stacked on the third light-transmitting electrode.
