Abstract: A display device whereby appropriate operation control desired by a user can be conducted is implemented even if an image for driver's seat which can be seen by a driver but cannot be seen by a passenger in a passenger seat and an image for passenger seat which can be seen by the passenger in the passenger seat but cannot be seen by the driver are displayed on a common screen. The display device comprises a unit for conducting operation control on an image with priority of an image GDR for driver's seat and an image GPA for passenger seat when an operation is performed to an operating switch arranged in such a manner that the operation area for the image GDR for driver's seat on the display screen and the operation area for the image GPA for passenger seat on the display screen overlap each other.

Abstract: Even if a driver's seat use picture able to be seen from a driver and not able to be seen from a passenger's seat passenger and a passenger's seat use picture able to be seen from a passenger's seat passenger and not able to be seen from the driver are displayed on the common screen, suitable operational control desired by a user is realized. Means are provided for judging whether operations on operating switches 42DR to 47DR and 42PA to 47PA arranged so that an operating region on the display screen for the driver's seat use picture GDR and an operating region on the display screen for the passenger's seat use picture GPA overlap are from the driver's seat direction or from the passenger's seat direction and performing operational control for the picture able to be seen from that direction.
