ORGANIC LIGHT EMITTING DISPLAY

摘要

PURPOSE: An organic light emitting display device is provided to improve accuracy of a pattern by reducing an interval between openings of a mask. CONSTITUTION: An organic light emitting display device(100) includes a plurality of pixels(110-140). Each pixel has first to third sub pixels(110R-140R,110G-140G,110B-140B). The first to third sub pixels are arranged in one direction. The first to third sub pixels emit the red, blue, and green light respectively. The light emitting layer of the first sub pixel includes a red light emitting layer and a blue light emitting layer. The light emitting layer of the second sub pixel includes the blue light emitting layer. The light emitting layer of the third sub pixel includes the green light emitting layer and the blue light emitting layer. Each sub pixel has a first electrode and a second electrode. The light emitting layer of each sub pixel is interposed between the first electrode and the second electrode.
