    Abstract: An organic EL image display device that includes a light emitting element substrate; and a circularly polarizing plate. The light emitting element substrate includes a reflecting layer and an organic electroluminescent layer group arranged in a matrix form on the reflecting layer. The reflecting layer, the organic electroluminescent layer group, and the circularly polarizing plate are arranged in this order. A polarization separation layer is provided between the organic electroluminescent layer group and the circularly polarizing plate, and includes polarization separation sites arranged in a matrix form corresponding to the organic electroluminescent layer group. The polarization separation site reflects light of one polarization state and transmits light of the other polarization state in light emitted from the corresponding organic electroluminescent layer. The polarization separation site is divided by a visible light transmission region. The organic EL image display device of the present invention has high brightness and little blurring.

    Abstract: A liquid crystal display includes: a first polarizer; a liquid crystal cell including a liquid crystal layer containing liquid crystal molecules horizontally aligned to a face of a substrate; and a second polarizer. The liquid crystal display further includes a first optical compensation film disposed between the first polarizer and the liquid crystal cell, an absorption axis of the first polarizer, an optical axis of the first optical compensation film, and an optical axis of the liquid crystal layer being parallel to each other in a view of the liquid crystal cell in a direction orthogonal to the face of the substrate of the liquid crystal cell. The optical axis of the liquid crystal layer of the liquid crystal cell and the optical axis of the first optical compensation film have a tilt angle from the face of the substrate of the liquid crystal cell in a same direction.
