A display system (1) having improved viewability and reduced in size and manufacturing cost has a display device (10) which includes an image forming layer (111) capable of emitting display light toward both front and back sides, and which can produce a display on a first surface (11) by a display lightportionemittedtowardthebacksideandproduceadisplay on a second surface (12) at the back of the first surface by a display light portion emitted toward the back side. The display also has an optical transmission control device (20, 21) which is placed along at least one of the first surface and the second surface, and which can control transmission of at least one of background light from a position at the back of the second surface as viewed from the first surface side and background light from a position at the back of the first surface as viewed from the second surface side. <IMAGE> |
