A screen unit is provided to realize a screen increasing the contrast of an image by providing a light absorbing layer on the rear surface of a reflection layer or the rear surface of the flexible base. A screen unit includes at least one blinding preventing layer, a reflection layer, a screen, a central axis fixing unit(30), and an ascending/descending unit(20). The screen is disposed on the rear surface of the screen and includes a flexible base changing the shape of the screen. The central axis fixing unit fixes a horizontal or vertical central axis of the screen. The ascending/descending unit moves a side edge of the screen by a predetermined distance in a projection direction and restores the side edge of the screen to a planar state. |
