Abstract
A projection image display includes: a screen unit that has a screen; a projection unit that projects an image onto the screen from a back surface of the screen; a housing that houses the projection unit; a slide mechanism that supports the screen unit such that the screen unit moves in an anterior-posterior direction; a locking mechanism that restricts a movement of the slide mechanism; and an adjustment mechanism that is capable of adjusting a position of the screen unit with respect to the housing from the outside while the locking mechanism restricts the movement of the slide mechanism.
