PROBLEM TO BE SOLVED: To provide an organic EL element having a circular polarization plate with improved coloring of reflection light.SOLUTION: An image display device includes an image display panel, at least one pattern phase difference layer, and a polarization element layer that are arranged in this order. The pattern phase difference layer includes first phase difference areas and second phase difference areas that are alternately arranged in a stripe pattern and have a difference from each other at least in one of in-plane slow axis direction and phase difference. |
