THREE-DIMENSIONAL DISPLAY DEVICE

摘要

[Problem] The object is to provide a three-dimensional display device that can be made thin, that has superior light efficiency, and that does not increase the number of components when compared to a structure for displaying a two-dimensional image. [Means for Resolution] A first light blocking film (12) has a plurality of first fixed openings (16) for forming a plurality of pixels (14), where a single pixel (14) is formed from a pair that is a right opening RO that is made from a first fixed opening (16) and a left opening LO that is made from a first fixed opening (16). A second light blocking film (20) has a plurality of second fixed openings that are located so as to have the respective centers thereof shifted with respect to centers of any of the first fixed openings (16). The light that passes through a second fixed opening (22) travels obliquely to a right opening RO and/or a left opening LO. The respective light directed toward the right opening RO or the left opening LO is controlled to be passed or be blocked by one shutter (26). The light that passes through the right opening RO and the light that passes through the left opening LO travel in directions that are away from each other on the outside of the first substrate (10).
