    摘要： A light emitting device and a manufacturing method thereof and a display used the light emitting device, in which fine patterning for the light emitting device is realized by a simple process and the light leakage is prevented and the efficiency at extracting light is increased, are provided. The light emitting device provides an organic electroluminescent (EL) device in which electrodes and a luminescent layer are formed, a diffraction grating or a zone plate, and a filter. Light emitted from the luminescent layer transmits through the diffraction grating or the zone plate, which is formed with a designated grating pitch, or is reflected at the diffraction grating or the zone plate. With this, the transmitting or reflecting light is controlled to be in a designated angle region. And when the light is transmitted through the filter, light having different color tone and chromaticity from those of the light emitted from the luminescent layer is extracted.

    摘要： A light-emitting body of the present invention includes an anode and a cathode at least partly facing the anode with the intermediary of a light-emitting material layer. An auxiliary electrode is formed, via an insulation layer, on the surface of the light-emitting body opposite to the surface where the anode faces the cathode via the light-emitting material layer. The cathode can be formed of a material that corrodes little. The light-emitting body therefore extends the life of a light-emitting device and therefore the life of a light-emitting display.

    摘要： An organic EL element which has no layer that prevents penetration of holes and electrons to the counter electrode. The organic EL element includes: an anode, a hole injecting and transporting layer formed on the anode, a light emitting layer formed on the hole injecting and transporting layer, an electron injecting and transporting layer formed on the light emitting layer, and a cathode formed on the electron injecting and transporting layer. Ip2≧Ip3 is established when an ionization potential of a constituent material for the light emitting layer is Ip2 and an ionization potential of a constituent material for the electron injecting and transporting layer is Ip3. Ea1≧Ea2 is established when an electron affinity of a constituent material for the hole injecting and transporting layer is Ea1 and an electron affinity of the constituent material for the light emitting layer is Ea2.
