Abstract
The present invention discloses an organic light-emitting diode (OLED) device with high color rendering comprising a base plate, a first conductive layer, a plurality of white light emitting layers, and a second conductive layer, wherein the spectra of the white light emitting layers possess characteristics of complementarities so as to enhance the color rendering of the emitted white light, and at least one carrier regulating layer is selectively disposed between every two white light emitting layers so as to increase the emitting efficiency and color rendering.
