ABSTRACT:
An apparatus for displaying an image on a screen of a CRT (Cathode Ray Tube) applicable to a vehicle is disclosed in which the visual angle controlling filter (liquid crystal panel) is disposed in a front space of the screen of the CRT. When the vehicle runs, a predetermined voltage is applied to the visual angle controlling filter so that the light from the screen to a driver's seat is interrupted. At this time, the application of the voltage to the visual angle controlling filter is detected and a color hue of the image appearing on the screen is controlled so that all viewers except the vehicle driver can view the image on the screen through the visual angle controlling filter with the same color hue as that viewed when the vehicle stops and no application of the voltage to the visual angle controlling filter.
