ORGANIC LIGHT EMITTING DEVICE, LIGHTING EQUIPMENT COMPRISING THE SAME, AND ORGANIC LIGHT EMITTING APPARATUS COMPRISING THE SAME

摘要

PURPOSE: An organic light emitting device, a lighting apparatus including the same, and a display apparatus inducing an organic light emitting apparatus are provided to improve light extraction efficiency by inserting a micro lens array between a transparent electrode and a transparent substrate. CONSTITUTION: A substrate includes a transmissive material. A first electrode(130) is located on the substrate. An organic light emitting layer(140) is placed on the first electrode. A second electrode(150) is placed on the organic light emitting layer. A first micro lens array is included between the substrate and the first electrode and has a refractive index larger than that of the substrate.
