Abstract
A projection display apparatus () includes slide bases () which are able to protrude from a housing (). A screen unit () is supported by rotation plates () rotatably provided on the slide bases (). The attaching and detaching operations of the screen unit () can be performed in a state where the slide bases () protrude from the housing () and the rotation plates () rotate to an operating position. In this operating position, the screen unit () is supported by the rotation plates () from below, so that the screen unit () can be prevented from being dropped on the floor, and therefore the reliability of the operations can be enhanced.
