Abstract:
1. A color conversion type organic electro-luminescent (EL) display, comprising: an organic EL substrate that includes a substrate, a lower reflective electrode, a bank, an organic EL layer comprising a plurality of portions separated by the bank, an upper transparent electrode, a color conversion layer separated by the bank, and a pixel region separated by the bank, and a color filter substrate in which a black matrix and a color filter are formed in a pattern on a transparent substrate, and which has a pixel region separated by the black matrix, the organic EL substrate and the color filter substrate being bonded and positioned such that the pixel region of the organic EL substrate and the pixel region of the color filter substrate are opposed, wherein the organic EL layer is sandwiched between the lower reflective electrode and the upper transparent electrode and has at least an emission layer made of a polymer material, and the color conversion layer is formed on the upper transparent electrode, absorbs EL light emitted by the emission layer and emits light with a wavelength different from that of the EL light.
