ABSTRACT:
An organic EL device and display are provided. A red light emitting layer, a green light emitting layer, a blue light emitting layer are laminated in this order between an anode and a cathode, and an intermediate layer “a” formed by use of an organic material is provided between the green light emitting layer and the blue light emitting layer. The HOMO-LUMO energy gap in the intermediate layer “a” is greater than the HOMO-LUMO energy gap of a green light emitting material constituting the green light emitting layer. In addition, the intermediate layer “a” has a hole transporting property. In the case of configuring a display by use of the organic EL devices, color filters are provided on the light take-out surface side. This makes it possible to provide an organic EL device with which light emission components for three colors of red, green and blue with a good balance suited to use for a full-color display can be obtained at a high luminance.
