A touch panel integrated type display apparatus has a display portion on one surface and a touch panel on the other surface. An input screen for operating the touch panel is displayed on a display plane of the display portion, and an operating position of the touch panel recognizable on the display plane referring to the input screen.

DETAILED DESCRIPTION In view of the circumstance described above, this invention intends to provide a touch panel integrated type display apparatus in which the display plane of a display portion is not got soiled by an input operation for a touch panel and cleanness of a high definition image is not deteriorated.
According to a first aspect of the invention, there is provided a touch panel integrated type display apparatus including: a display portion provided on one surface of the touch panel integrated type display apparatus, the display portion having a display plane; and a touch panel provided on the other surface of the touch panel integrated type display apparatus, wherein an input screen for operating the touch panel is displayed on the display plane of the display portion, and an operation position on the touch panel is recognizable on the display plane referring to the input screen.
In this configuration, a user can perform an input operation without touch to the display plane of the display portion.
Therefore, no finger print or dirt will be deposited on the display plane and cleanness of a high definition image displayed on the display portion is not deteriorated.
In addition, since the user can recognize the operation position from the display plane, the operability is not lost.
According to a second aspect of the invention, the touch panel and the display portion have optical transparency so that the operation position on the touch panel is visually recognizable from the display portion.
In this configuration, where the user performs an input operation with a touch of a finger or a pen to the input detecting portion of the touch panel, the user can perform the input operation while seeing, from one display plane, the finger or pen operating the touch panel on the other plane.
This permits an easy and sure input operation.
According to a third aspect of the invention, the display portion is constructed of an organic EL display device.
Since the organic EL display device spontaneously emits light, it does not have an illuminating section such as a backlight or front light which impedes optical transparency, as used in a liquid crystal display device
