Abstract:
An organic EL light-emitting apparatus includes a base, an organic EL device, a prism member, a polarizing member, and a phase member. The prism member, the polarizing member, and the phase member are adjacent to a light extraction side of the organic EL device. The prism member includes a plurality of unit prisms each having a triangular-column shape. The unit prisms are arranged such that their longitudinal directions are parallel to one another. The polarizing member is disposed further from the base than the prism member. The prism member has an apex angle between 90° to 140°.
