PROBLEM TO BE SOLVED: To solve the problems that a reflected image of a display unit is easily reflected in a windshield if the area of the display unit inside a vehicle is increased, and that the visual field of the windshield is impaired. SOLUTION: A visual field control film 16 for allowing the light at the angle of incidence within a range of the predetermined control angle (±α) with respect to the perpendicular of a cover 14 to be scattered thereby and allowing the light at the angle other than the control angle to be transmitted therethrough is provided on the cover 14 facing the display unit 15. When the windshield 13 is in the range of the control angle from a display facing area β of the cover 14 when viewed from a reference visual point I, any reflected image of the display unit 15 is not reflected in the windshield 13, and the area of the display unit 15 can be increased. |
