    • An organic light emitting device includes: a first electrode disposed on a substrate; a pixel defining layer disposed on the substrate e and patterned so that at least a portion of the first electrode is exposed in a light emitting region; a hole injection layer disposed over the pixel defining layer and the at least a portion of the first electrode exposed in the light emitting region; an organic thin film layer disposed over the hole injection layer; an electron injection layer disposed over the organic thin film layer; and a second electrode disposed on the electron injection layer, the second electrode having an opening configured to expose the electron injection layer in the light emitting region. The organic light emitting device may be implemented in a display device having excellent color-reproduction, when applied to the display device using white light as a light source and the large area display device.
    • 一种有机发光器件,包括:设置在基板上的第一电极; 设置在所述基板e上并且被图案化以使得所述第一电极的至少一部分在发光区域中暴露的像素限定层; 设置在像素限定层上方的空穴注入层和暴露在发光区域中的第一电极的至少一部分; 设置在所述空穴注入层上的有机薄膜层; 设置在所述有机薄膜层上的电子注入层; 以及设置在所述电子注入层上的第二电极,所述第二电极具有用于使所述发光区域中的电子注入层露出的开口。 当应用于使用白光作为光源的显示装置和大面积显示装置时,有机发光装置可以实现在具有优异的色彩再现的显示装置中。
