Organic light emitting device

摘要

A full color light emitting device having a reduced driving voltage includes a substrate having a first subpixel, a second subpixel, and a third subpixel. A plurality of first electrodes are in the first subpixel, the second subpixel, and the third subpixel. A second electrode faces the first electrode. An emission layer is between the first electrode and the second electrode. The emission layer includes a first emission layer in the first subpixel for emitting a first color light in the first subpixel, a second emission layer in the first subpixel for emitting a second color light in the second subpixel, and a third emission layer in the first subpixel, the second subpixel and the third subpixel, for emitting a third color light in the third subpixel. The third emission layer includes at least one compound represented by Formula 1:;
