a screen disposed on a front side of the display plane of the projection display device; and
a screen driving device that moves the screen to thereby switch between a first state where the display plane of the projection display device is covered with the screen and a second state where the display plane of the projection display device is visible from the front.
2. The display apparatus according to claim 1, the projection display device comprising:
a light source;
a liquid crystal device that modulates light emitted from the light source; and
a projection optical system that enlarges and projects light modulated by the liquid crystal device onto the back side of the display plane.
3. The display device according to claim 1, the screen having a belt-like shape extending in a moving direction of the screen, and comprising a light transmission window that enables the display plane of the projection display device to be visible in the second state.
4. The display device according to claim 3, the screen driving device comprising:
a pair of rollers that winds and unwinds the screen; and
a roller driving device that rotatably drives the pair of rollers to switch position of the screen between the first state and the second state.
5. The display device according to claim 3, a plurality of information being provided at a front side of the screen in a longitudinal direction of the screen, and the screen driving device intermittently driving the screen in the first state to thereby display the plurality of information by the screen while switching.
6. The display device according to claim 1, the screen driving device comprising:
a drive control section that positions the screen in the first state in daytime, and that positions the screen in the second state in nighttime.
7. A display apparatus, comprising:
a projection display device having a display screen member;
a first roller part disposed on a first side surface of the projection display device;
a second roller part disposed on a second side surface of the projection display device opposing the first side surface;
a screen disposed along the display screen member of the projection display device with one end attached to the first roller part and another end attached to the second roller part;
a projection part provided on the screen that enables a displayed image from the projection display device to be visible; and
an information area formed on the screen.
8. The display device according to claim 7, further comprising a drive control section that controls rotation of the first roller part and the second roller part and that moves the screen.
9. The display device according to claim 8, the drive control section comprising a time control part, and moving the screen when a predetermined time is reached.
10. The display device according to claim 7, the screen being detachable with respect to the projection display device.
11. The display device according to claim 7, the projection part of the screen being a window that exposes the display screen member of the projection display device.
12. The display device according to claim 7, the projection part of the screen projecting a displayed image of the projection display device onto the screen.
13. The display device according to claim 12, further comprising a stretching part that stretches the screen at least on both sides of the projection part of the screen.
14. An information display system, comprising:
a projection display device having a display section;
a display apparatus disposed along the display section of the projection display device and having at least one image area and a screen including a display area that enables displayed information from the projection display device to be visible; and
an information supply section that transmits displayed information to the display apparatus.
15. The information display system according to claim 14, the display apparatus and the information supply section communicating information bidirectionally via lines.
16. The information display system according to claim 14, the display apparatus having a self-check function, and transmitting abnormal information of the display apparatus to the information supply section when an abnormality is determined.
