Abstract: Disclosed is an organic light emitting display device. The organic light emitting display device including a plurality of pixels provided on a substrate. The plurality of pixels each include a first emissive area emitting light in a first surface direction of the substrate, a reflective area reflecting incident light in the first surface direction of the substrate, and a second emissive area overlapping the reflective area and emitting light in a second surface direction opposite to the first surface direction of the substrate. The organic light emitting display device may further include an auxiliary color filter provided in the first emissive area. In the organic light emitting display device, since a polarizer is replaced with a color filter, a light transmittance and a color reproduction rate are enhanced, and bidirectional image display is realized through the second emissive area.

Abstract: An OLED display device which prevents a color change according to a viewing angle. The OLED display device may include a substrate defined by a first pixel, a second pixel, a third pixel and a fourth pixel; an anode electrode on the substrate; a first organic light-emitting layer for emitting a first color light; a second organic light-emitting layer for emitting a second color light; a cathode electrode formed of a semi-transparent metal material on the first or second organic light-emitting layer, wherein the first organic light-emitting layer is formed in the first pixel and the second pixel; the second organic light-emitting layer is formed in the second pixel, the third pixel and the fourth pixel; and the second pixel emits mixed light of the first color light and the second color light.
