Abstract: A display apparatus is disclosed that includes a first display area and a second display area adjacent to the first display area. The first and second display areas include first and second light emitting areas having first and second pixel densities, respectively. The first and second light emitting areas at an interface between the first and second display areas are arranged such that in operation light emitted by the first and second light emitting areas produces a gradual decrease in light intensity from the first display area to the second display area near the interface.
