    • PURPOSE: An organic light emitting display device is provided to improve luminous efficiency by preventing the overlap of light emitted from an organic light emitting layer and external light. CONSTITUTION: An organic light emitting layer(720) is located on a first electrode. A second electrode(730) is located on the organic light emitting layer. A first selective reflection layer is located on the first electrode. A third semi-transparent electrode is formed on the first selective reflection layer. The organic light emitting layer includes a first sub light emitting layer, a second sub light emitting layer, and a third sub light emitting layer. The first selective reflection layer reflects the light of a first wavelength corresponding to blue light emitted from the first sub light emitting layer.
    • 目的:提供一种有机发光显示装置,通过防止从有机发光层发射的光和外部光的重叠而提高发光效率。 构成:有机发光层(720)位于第一电极上。 第二电极(730)位于有机发光层上。 第一选择反射层位于第一电极上。 在第一选择反射层上形成第三半透明电极。 有机发光层包括第一副发光层,第二副发光层和第三副发光层。 第一选择反射层反射与从第一副发光层发射的蓝色光对应的第一波长的光。
