An organic light-emitting device (OLED) is disclosed. The OLED includes a pixel electrode; a counter electrode; and at least an emission layer between the pixel electrode and the counter electrode, wherein a total thickness of the organic layer including an emission layer emitting blue light is 3000-3600 Å. According to the OLED of the present disclosure, the incidence of dark spots can be remarkably reduced without degradation of color purity and efficiency, and thus the flat display including the OLED has improved reliability.
