More Information
Summary:An object of the present invention is to maintain sufficient light extraction from an organic light emitting device and reduce reflection of external light. There are arranged a polarizing member, a prism member, a phase member, and an organic light emitting element which has an organic light emitting layer arranged between a pair of electrodes, in mentioned order from the side of a light extraction surface. When the prism member includes two sheets, the vertex angle of the prism member sheet arranged on the side of the organic light emitting element is preferably a vertex or less of the prism member arranged on the side of the light extraction surface. Furthermore, the prism members are preferably arranged so that pitch directions thereof are orthogonal to each other.
