| abstract |
In an organic EL device comprising organic layers between a pair of electrodes participating in at least a light emitting function, at least one organic layer contains an organic compound selected from naphthacene, tetraaryldiamine, anthracene and quinoxaline derivatives as a host material and an organic compound having a specific skeleton, typically diindeno[1,2,3-cd:1',2',3'-lm]perylene derivative as a dopant. The device is capable of light emission to a satisfactory luminance, especially in a long wavelength region, and with a chromatic purity sufficient for use in full color displays, and had a sufficient durability to sustain such improved light emission performance over a long time. |
