Abstract: A display device includes a display unit that includes a plurality of light emitting areas; a plurality of touch electrodes disposed between the plurality of light emitting areas and that sense a touch; a light blocking member that forms a code pattern by covering a portion of a front surface of at least one of the plurality of touch electrodes with a preset code shape; and a reflective electrode formed on a rear surface of the light blocking member and that has an area that at least partially overlaps the light blocking member and reflects light from the front surface.

Abstract: A display device includes an active region including pixels receiving data signals through data lines, and a non-active region on a side of the active region in a first direction and including a pad portion. The display device includes non-active fan-out wirings in the non-active region and connected to the pad portion, signal wirings extending in the first direction across the active region and connected to the pixels, and connection wirings passing through the active region and connecting some of the non-active fan-out wirings and some of the signal wirings. Each of the connection wirings includes first and second extension portions made of a first conductive layer, and a third extension portion made of a second conductive layer different from the first conductive layer. The first and second extension portions extend in the first direction, and the third extension portion extends in a second direction intersecting the first direction.
