Abstract:
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.
