Abstract

An organic light-emitting display device is disclosed. The organic light-emitting display device includes an emission layer formed between two electrodes disposed over a substrate, wherein the emission layer includes a host including fluorescent materials and a dopant including phosphorescent materials, and a host PL region formed by the host of the fluorescent materials has a spectrum overlapped with part of a dopant UV absorption region formed by the dopant of the phosphorescent materials.

Description

technical field [0001] The invention relates to an organic light emitting display device. Background technique [0002] An organic light emitting element used in an organic light emitting display device is a light emitting element in which a light emitting layer is formed between two electrodes placed on a substrate. [0003] Organic light emitting display devices include a top emission method, a bottom emission method, and a dual emission method according to a light emission direction. [0004] The organic light emitting display device adopts a method of realizing an image using an organic light emitting element emitting red, green, and blue light, and a method of realizing an image using an organic light emitting element emitting white light and red, green, and blue color filters. [0005] Using the host-dopant system can maximize the performance of the light emitting material of the organic light emitting display device. In this case, an important factor is the smooth e...
