摘要： An image display apparatus includes a storage display element having a screen portion which receives image light from its back side and stores and displays an image, and a light blocking mechanism. The light blocking mechanism is capable of being switched over between a light-blocked state in which the light blocking mechanism blocks light incident on the front side of the screen portion of the storage display element to shut off incidence of external light on the screen portion, and an observation-possible state in which the light blocking mechanism unblocks light incident on the front side of the screen portion of the storage display element.
