Abstract:
The present invention provides an organic EL image display device including a reflecting layer, an organic electroluminescent layer group, a polarization separation layer, and a circularly polarizing plate in this order, in which the polarization separation layer 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 layer is divided by a visible light transmission region to form the polarization separation sites, and a wavelength range of the reflection is wider than a wavelength range of the light emission. The organic EL image display device according to the present invention has high brightness at the time of both front observation and oblique observation and little image blurring.
