Abstract:
1. An organic EL panel comprising: a plurality of organic EL elements each comprising an organic layer provided between first and second electrodes and emitting light when a voltage is applied between the first and second electrodes to allow a current to flow in the organic layer; wherein each organic EL element corresponds to a different color, and one of the organic EL elements corresponds to a single color to be intensified; in only the organic EL element corresponding to the single color to be intensified, a semi-transmissive layer which reflects a portion of light emitted from the organic layer is positioned adjacent to the first electrode; the second electrode includes a reflective layer for reflecting light emitted from the organic layer; the first electrode and the second electrode are structured such that a distance between an underside of the first electrode and the second electrode is identical for all of the organic EL elements of every color, the distance corresponding to a predetermined optical length, such that when light generated in the organic layer is repetitively reflected between the reflective layer and the semi-transmissive layer, an interval between the reflective layer and the semi-transmissive layer functions as a microresonator which intensifies and selects light having a specific wavelength corresponding to the single color to be intensified and ejects the selected light through the semi-transmissive layer; each organic EL element comprises a color filter for limiting color of the light ejected from the organic EL element; and the organic layer of each organic EL element emits white light; and wherein color filters are provided for three pixels that emit light of different colors, a microresonator micro-cavity being provided for only one of the three pixels having the color filters.
