Abstract
A picture display apparatus avoids becoming less stable when a display body with a projection device is raised. A projector board stand includes a projector that projects a picture, a display body including a display surface to display the picture projected by the projector, and a body support supporting the display body. The projector is supported on the display body and protrudes in a front direction to project the picture on the display surface. The body support includes a lift unit that raises and lowers the display body. The lift unit moves the display body in a rear direction when the display body is raised.
