Claim:
1. An organic light emitting device with red, green, blue and white subpixel regions, comprising: a lower substrate; an anode formed on the lower substrate; an organic emission layer formed on the anode, the organic emission layer emitting white light; a cathode formed on the organic emission layer; and a reflection decreasing layer formed on a part of the cathode corresponding to the white subpixel region for reducing reflection of the light emitted from the organic emission layer by the cathode at the white subpixel region, wherein the reflection decreasing layer includes a first reflection decreasing layer and a second reflection decreasing layer, and wherein the first reflection decreasing layer is formed on an upper surface of the cathode and the second reflection decreasing layer is formed on a lower surface of the cathode corresponding to the white subpixel region.
