Abstract: A display device includes: a display panel; a first light emitting driving circuit to provide first emission signals; and a second light emitting driving circuit to provide second emission signals. The display panel includes: a plurality of pixels, each including a first light emitting element and a second light emitting element; and a light control pattern overlapping with the second light emitting element of each of the plurality of pixels in a plan view. Each of the plurality of pixels is to emit light through the first light emitting element when a corresponding first emission signal is at an active level, and emit light through the second light emitting element when a corresponding second emission signal is at the active level. A part of the first emission signals and the second emission signals remains at an inactive level during at least one frame based on an operating mode.
