Abstract
Provided is an organic light emitting device (OLED) having increased optical extraction efficiency. The OLED includes a transparent substrate, an optical path control layer made of an optical transmittance material on the transparent substrate, a transparent electrode, an organic light emitting layer that generated light, and a reflection electrode formed on the organic light emitting layer, which are sequentially stacked. The refractive index And thickness of the optical path control layer are optimized.
