  • Organic EL element and organic EL panel
    Patent number: 7839084
    Abstract: A light-emitting device may include a light-emitting element, a microresonator, and a color filter. The light-emitting element may include first and second electrode and an emissive layer provided between the first and second electrodes, and may emit light of a predetermined color when a voltage is applied between the first and second electrodes to allow a current to flow in the emissive layer. The microresonator may repetitively reflect light of a predetermined color emitted from the emissive layer within an interval having an optical length corresponding to the predetermined color, and thereby intensifying and selecting the light of the predetermined color. The color filter may pass the light intensified and selected by the microresonator and further limiting to light having a wavelength of the predetermined color.
