Abstract
A semi-transmissive reflection sheet is provided, including a first optical shape layer including unit optical shapes, and a second optical shape layer laminated on the first optical shape layer from a side of a surface formed by the unit optical shapes. The unit optical shape has a first surface that is inclined with respect to a light emergent side surface of the second optical shape layer. The light emergent side surface is opposed to the first optical shape layer. The unit optical shape also has a second surface that is not parallel to the light emergent side surface. A reflection layer that reflects at least a part of image light traveling in the semi-transmissive reflection sheet is provided on the first surface.
