Abstract
An organic light emitting device includes an anti-reflection film including a polarizer and a compensation film positioned on the polarizer and including a liquid crystal layer which includes liquid crystals oriented in a direction tilting obliquely with respect to a surface of the liquid crystal layer extending in a horizontal direction in a cross sectional view, tilt angles of the liquid crystals are gradually larger from the first side to the second side, a maximum tilt angle of the liquid crystals with respect to the surface of the liquid crystal layer is from about 15° to about 80°, and in-plane retardation (R) of the liquid crystal layer for incident light of a 450 nm wavelength and a 550 nm wavelength satisfies a Relationship 1.
