Abstract

In an on-board display apparatus, a transmission type display device is provided on a forward and displays a touch switch display when necessary, and the operability as a touch panel is ensured. The transmission type display device can be turned to be transparent, and an image display device is provided on a backward of the transparent portion. Since the display screen of the image display device is backward, the visual range is long, and the visibility can be improved. Since the display screen of the image display device and the display screen of the transmission type display device are not on the same plane, even if the touch switch display is touched by a finger, an image can be seen, and a pointer can be displayed on the display screen of the image display device in a position corresponding to the touched position, and thus the operability can be improved.

18. The display apparatus according to claim 13, wherein the display apparatus is mounted on a vehicle, and the approach detecting portion distinguishes whether the operation object is approaching in a direction from a driver seat or a passenger seat.

20. The display apparatus according to claim 1, wherein the transmission type display portion is constituted by a curved surface.

21. The display apparatus according to claim 1, wherein the transmission type display portion covers the display portion such that the display portion can be seen.

22. The display apparatus according to claim 17, wherein the display apparatus is provided in a middle portion between a driver set and a passenger seat.

23. The display apparatus according to claim 1, further comprising:

an operation switch adjacent to the transmission type display portion,

wherein the operation switch is displayed selectively in the transmission type display portion.

24. The display apparatus according to claim 17, wherein the transmission type display portion has a curved plate shape, and an inclination angle with respect to a floor surface of a vehicle is larger in a lower portion than in an upper portion of the transmission type display portion.

25. The display apparatus according to claim 1, wherein the transmission type display portion has a curved plate shape, and the display portion is a flat plate shape.

26. The display apparatus according to claim 1, wherein the transmission type display portion is formed of an organic EL (Electro Luminescent) layer, and the display portion is formed from a liquid crystal display apparatus.

27. The display apparatus according to claim 1, wherein a display area of the transmission type display portion is larger than that of the display portion.

28. The display apparatus according to claim 1, wherein a portion of the transmission type display portion is turned to be a transparent so that display of the display portion can be seen.

29. The display apparatus according to claim 1, wherein display of an operation switch displayed in the transmission type display portion is controlled such that the display appears or disappears gradually.

30. The display apparatus according to claim 1, wherein display of the transmission type display portion is controlled so as to be selectively opaque so that the display portion cannot be seen.

31. The display apparatus according to claim 1, wherein display of the transmission type display portion is provided pivotally with one end thereof as a supporting point.

4. A display apparatus comprising:

a transmission type display portion that is provided with a touch panel function and can display an image on a transparent surface,
