Abstract
One pixel is divided into a first region including a first light emitting element and a second region including a second light emitting element, wherein the first region emits light in one direction and the second region emits light in the direction opposite to that of the first region. Independently driving the first light emitting element and the second light emitting element allows images to be displayed independently on the surface.
