To provide a unidirectional image display panel that allows only images to be seen from the outside, while making the inside invisible, allows the outside to be seen from the inside as if through a corrugated plate glass, and receives light to the inside in the same way as the corrugated plate glass, and which can be used as a blinder.

The unidirectional image display panel is configured by sticking a projection image to one of planes holding a right angle of a rectangular prism between them, bonding two rectangular prisms at planes, to which the projection image is stuck, to obtain an attached member. A plurality of constitution units are attached to one side of planes of the transparent supporter by using the attached member as a constitution unit in parallel so that a ridge line is extended to the same direction.
