ABSTRACT:
An organic EL device and display are provided. An organic EL device which has light emission components in three colors of red, green and blue in a good balance suited to use for a full-color display and which is capable of highly efficient and stable light emission for a long time. In the organic EL device including an organic layer having light emitting layers sandwiched between an anode and a cathode, the light emitting layers include a red light emitting layer, a green light emitting layer, and a blue light emitting layer laminated in this order from the side of the anode. The red light emitting layer contains a hole transporting light emitting material and has a hole transporting property. In addition, the green light emitting layer has a positive and negative charge transporting property. Furthermore, the blue light emitting layer has an electron transporting property, and includes a positive and negative charge transporting blue light emitting layer and an electron transporting blue light emitting layer laminated in this order from the side of the anode.
