A display device includes a first pixel unit located on a substrate and including a first micro-LED, a second pixel unit located on the substrate and including a second micro-LED having a differently colored emission and a different level of luminous efficiency from the first micro-LED, and an emission controller that controls light intensities of the first micro-LED and the second micro-LED. The first pixel unit includes a first current control switch and a first period control switch. The second pixel unit includes a second current control switch and a second period control switch. The first current control switch, the first period control switch, the second current control switch, and the second period control switch are connected to the emission controller.
