Abstract:
A display device, includes a substrate having at least two colored subpixels and a white subpixel separately arranged thereon; a first anode having a first thickness at each of the colored subpixels on the substrate; a second anode, having a thickness smaller than the first thickness, at the white subpixel on the substrate; an organic stack comprising a first stack having a first blue emission layer, a second stack having a second blue emission layer, and a third stack having at least one of emission layers having a longer wavelength than the blue emission layers, which are provided in sequence on the first anode in the colored subpixel and the second anode in the white subpixel; a cathode over the organic stack; and a compensation pattern between the second anode and the substrate.
