ABSTRACT:
An electroluminescence panel having an electroluminescence element in each pixel, wherein the electroluminescence element comprises an emissive element layer having at least a light emitting function between a reflective film and a semi-transmissive film which is provided opposing the reflective film and have portions having different cavity lengths in one pixel, the cavity length being a distance between the reflective film and the semi-transmissive film. Such a structure can be realized, for example, by changing a thickness of a transparent electrode which is a lower electrode of the element. Because peak wavelength that can be intensified can be varied among regions in one pixel having different cavity lengths, a viewing angle dependency is improved.
