Abstract
An organic light emitting device (OLED) includes a polymeric fluorescent light emitting material doped with a phosphorescent dopant to form a fluorescent light emitting layer. The fluorescent light emitting layer may inhibit or prevent device degradation without affecting light emission from the light emitting layer, and may improve the service life of the OLED.
