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.
