Abstract
There is provided an organic electroluminescent display apparatus including a plurality of pixels constituting a display portion, each of the pixels includes sub-pixels of at least four colors, each of which includes an organic electroluminescent device having a pair of the electrodes and an organic compound layer formed between the pair of the electrodes, and the sub-pixels of at least four colors constitute a convex polygon containing a white color on CIE chromaticity coordinates, and includes the sub-pixels of two colors to be complementary colors with the white color interposed therebetween. In this case, the organic compound layers of the sub-pixels of two colors each contain a phosphorescent organic compound. The organic electroluminescent display apparatus can enlarge the color gamut and simultaneously can reduce the power consumption.
