An organic light emitting device utilizing the micro-cavity effect in the RGB subpixel regions while suppressing the micro-cavity effect in the white subpixel region is provided. The organic light emitting device includes a lower substrate, an anode formed on the lower substrate, an organic emission layer formed on the anode, a cathode formed on the organic emission layer, and a reflection decreasing layer formed on at least a portion of the cathode for reducing reflection of the light emitted from the organic emission layer by the cathode to reduce the micro-cavity effect. Such a selective use of the micro-cavity effect in the organic light emitting device improves the color accuracy, the luminance efficiency and the lifespan of the top emission type organic light emitting device.
An organic light emitting device with red, green, blue and white subpixel regions, comprising:
An organic light emitting device, comprising:
A method of manufacturing an organic light emitting device with a first part corresponding to red, green, blue subpixel regions and a second part corresponding to a white subpixel region, the method comprising:
