Abstract:
This optical display medium having a display surface comprises: a reflective polarizer layer provided in a reflective region RL which is a part of or the entire region of the display surface; and a birefringent layer provided further to a viewing side than the reflective polarizer layer and provided to a region RA which occupies a part of the reflective region RL. The reflective polarizer layer is a layer that reflects incident light as circularly polarized light or linearly polarized light.
