Abstract: Discussed is an organic light emitting display device, including a plurality of pixels. Each pixel includes a red sub pixel, green sub pixels, and a blue sub pixel. The red sub pixels and the blue sub pixels are aligned in a first direction. The green sub pixels are disposed between the red sub pixel and the blue sub pixel. The red sub pixel, the green sub pixels, and the blue sub pixel of a first pixel form a first group, and the red sub pixel, the green sub pixels, and the blue sub pixel of a second pixel form a second group. The first group and the second group are symmetric with the first direction. The red sub pixels and the blue sub pixels are disposed at a second line parallel to a second direction perpendicular to the first direction.

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.
