Abstract: An onboard image display device for a vehicle includes a projector that projects an image including information conveyed to a passenger, the information including a state of a vehicle and a warning, the projected image being displayed on a window glass of the vehicle. The projector is provided in a space which is formed by a plate-shaped member in the vehicle. For example, the projector is mounted in an inner panel reinforcement of an inner panel of a side door. That is, the projector is mounted within a space which is originally provided by the inner panel reinforcement to ensure reinforcement function. Image light from the projector is projected on the window glass of the side door.

Abstract: A display device for a vehicle is provided in a vehicle having idling stop function and includes: a fuel economy display unit to display fuel economy information on the vehicle; an first fuel economy display unit to calculate a first fuel economy based on a distance traveled and fuel consumption in a first period; and a second fuel economy calculation unit to calculate an second fuel economy based on a distance traveled and fuel consumption in a second period shorter than the first period. The device also includes a display control unit to control display of the fuel economy display unit based on a fuel economy difference between the first and second fuel economies. When the second fuel economy reaches a reference value before performing idling stop, the fuel economy display control unit controls the fuel economy display unit based on the last fuel economy difference without updating the difference.
