    Abstract: A display device includes a display panel, a left scan driver, a right scan driver, and a central scan driver. The display panel has a display area in which an image is displayed, and a non-display area in which an image is not displayed. The left scan driver and the right scan driver are respectively arranged in left and right non-display areas of the display panel. The central scan driver is arranged in a central area of the display panel. Subpixels adjacent to the central area of the display panel are small in size compared to subpixels arranged in other areas of the display panel.

    Abstract: An electroluminescent display is disclosed. Each of subpixels included in the electroluminescent display includes a first driver including a first driving element for driving a light emitting element during a first period, and a second driver including a second driving element for driving the light emitting element during a second period. The light emitting element includes an anode connected to the first and second drivers and a cathode supplied with a low potential power voltage. During the first period, a high potential power voltage higher than the low potential power voltage is supplied to the second driving element, and the low potential power voltage is supplied to the first driving element. During the second period, the high potential power voltage is supplied to the first driving element, and the low potential power voltage is supplied to the second driving element.
