ANISOTROPIC REFLECTION DISPLAY UNIT, AND INFORMATION STORAGE UNIT USING ANISOTROPIC REFLECTION DISPLAY UNIT

摘要

An anisotropic reflection display unit of the present invention is an optically transparent anisotropic reflection display unit (1) which includes a plurality of reflective sheets (3) inside a thin-film reflective sheet holding layer (2). The reflective sheets (3) are inclined in a constant direction and at a constant angle with respect to the plane of the reflective sheet holding layer (2). Light incident from a first specific direction is reflected by the surface of a reflective sheet (3) and does not pass through the reflective sheet holding layer (2). Light incident on a reflective sheet (3) from a second specific direction is reflected by the surface of the reflective sheet (3), reflected again by the backside of an adjacent reflective sheet (3), and passes through the reflective sheet holding layer (2). The light may be reflected several times before passing through.
