Abstract:
In one aspect, a cathode including the first metal layer, the transparent conductive layer formed on the first metal layer, and the second metal layer formed on the transparent conductive layer is applied to the organic light emitting device and thicknesses of the first metal layer, the transparent conductive layer, and the second metal layer are controlled so that the external light reflection of the organic light emitting device is prevented. The cathode may further include the third metal layer formed on the second metal layer.
