Abstract
To provide a display device capable of controlling the viewing angle. [Solution] A display device according to one embodiment of this specification comprises a display area in which a plurality of subpixels are arranged, each of the plurality of subpixels including a first light-emitting element, a second light-emitting element, and a pixel circuit commonly connected to the first and second light-emitting elements, the first cathode electrode of the first light-emitting element and the second cathode electrode of the second light-emitting element being separated from each other, and the voltage applied to the first cathode electrode and the second cathode electrode changing according to the viewing angle control mode. One light-emitting element can emit light at a wide viewing angle, and the other light-emitting element can emit light at a narrow viewing angle. With this configuration, it is possible to electrically switch between a wide viewing angle mode and a narrow viewing angle mode without using a mechanical filter, so that the viewing angle can be adjusted while maintaining high brightness and high image quality.
