Organic light-emitting diode display device

An organic light-emitting diode display device comprising:

• a substrate having an upper surface and a lower surface opposite the upper surface;
• an active element array disposed on the upper surface side of the substrate;
• at least one organic light-emitting diode (OLED) disposed over the substrate, the OLED comprising:
• a first electrode disposed on a side adjacent to the active element array;
• a second electrode disposed opposite to the first electrode;
• and
• an organic light-emitting layer interposed between the first electrode and the second electrode;
• a light absorption layer disposed between the OLED and the upper surface of the substrate, or disposed on the lower surface of the substrate, wherein an average reflectance of the light absorption layer in a wavelength range of visible light is less than 0.3;
• and
• an encapsulation plate disposed over the second electrode.
