Abstract: A display device comprises a first display area, a second display area adjacent to a side of the first display area, a third display area adjacent to a side of the second display area, a plurality of emission areas disposed in the first, second, and third display areas to emit light, and a light blocking layer surrounding the plurality of emission areas. A width of the light blocking layer between adjacent emission areas in a first direction in each of the first and third display areas is greater than a width of the light blocking layer between adjacent emission areas in the first direction in the second display area.

Abstract: A display device includes a display unit including a plurality of emission areas, a plurality of touch electrodes that sense a touch, a plurality of code patterns that cover a part of a front surface of at least one of the plurality of touch electrodes, and a plurality of light-blocking dummy patterns formed on some of the plurality of touch electrodes on which the plurality of code patterns is not formed. Each of the touch electrodes includes at least one portion disposed between adjacent emission areas among the plurality of emission areas. A thickness of the plurality of code patterns is different from a thickness of the light-blocking dummy patterns, and a light-blocking rate of the plurality of code patterns is different from a light-blocking rate of the light-blocking dummy patterns.
