    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.

    Abstract: A display device 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 overlapping the first light-transmitting electrodes and 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 source 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 that at least partially overlaps the first light-transmitting electrode in the plan view with an insulating layer interposed therebetween. An area of the third light-transmitting electrode in the pixel in a display region closer to the light source is larger than an area of the third light-transmitting electrode in the pixel in a display region farther from the light source.

    Abstract: According to an aspect, a display device includes: a cover member curved when viewed in a first axis direction along a first axis; and a display panel disposed on one side of the cover member. The cover member has a first surface facing the display panel and a second surface on the opposite side of the first surface. The first surface forms a straight line and at least a part of the second surface forms a curved line in a cross-section orthogonal to a second axis that is along a straight line extending from one end to the other end of the cover member when viewed in the first axis direction.
