Abstract: A display panel includes a pixel unit including a plurality of pixels which emits light of different colors from each other, and a light blocking element disposed on the pixel unit and blocking a portion of light emitted from each of the plurality of pixels. Each of the plurality of pixels includes a pixel circuit, a first light emitting element electrically connected to the pixel circuit, and a second light emitting element electrically connected to the pixel circuit, where the second light emitting element emits light of a same color as light emitted from the first light emitting element. The light blocking element blocks a portion of light emitted from the first light emitting element and traveling in a first direction, and blocks a portion of light emitted from the second light emitting element and traveling in a second direction opposite to the first direction.
