Patent ID: 7548019

Claim:
An electroluminescence panel having an electroluminescence element in each pixel, wherein the electroluminescence element in each pixel has a layered structure with an emissive element layer having at least a light emitting function provided between a reflective film and a semi-transmissive film which opposes the reflective film, the electroluminescence element having a microcavity in which a cavity length which is a distance between the reflective film and the semi-transmissive film is set to intensify light of a predetermined wavelength, each pixel, which is a minimum unit of light emission, has portions having different cavity lengths, the electroluminescence element has an emissive element layer between a transparent electrode and a metal electrode, a semi-transmissive film is provided external to the transparent electrode, the metal electrode functions as a reflective film, the microcavity comprises the transparent electrode and the emissive element layer, a thickness of the transparent electrode is varied within each pixel to provide the portions having different cavity lengths, and an insulating layer is provided covering a step portion, of the transparent electrode, in which the thickness is varied.
