WHITE ORGANIC LIGHT-EMITTING DEVICE, CAPABLE OF ADJUSTING A WHITE COLOR PROPERTY BY ADJUSTING THE AREA OF A RED-GREEN COLOR REGION, A RED COLOR REGION OR A BLUE COLOR REGION

摘要

PURPOSE: A white organic light-emitting device is provided to improve the properties of a red color element and a blue color element by including a blue color emitting region and a red color emitting region which independently function in one pixel.;CONSTITUTION: A light emitting layer is formed between a first electrode and a second electrode. The light emitting layer includes a first light emitting layer and a second light emitting layer. The first light emitting layer includes a red-green color emitting region and a blue color emitting region. A common layer is formed between the first electrode and the light emitting layer or between the second electrode and the light emitting layer. The common layer is selected from a group including a hole-implanting layer, a hole-transporting layer, an electron-implanting layer, and an electron-transporting layer.;COPYRIGHT KIPO 2010
