ABSTRACT:
An apparatus for displaying a television image on a television monitor applicable to a vehicle passenger compartment. In the television image displaying apparatus, the television monitor is installed on a center console of a vehicle passenger compartment. A liquid crystal filter is arranged on a television monitor screen which has variable transmittance according to a voltage applied across a whole surface electrode thereof. The liquid crystal filter serves to limit an angle of visible field around a driver's seat position with a front passenger seat position being provided a high image transmittance. In addition, a louver type filter is arranged between the TV monitor screen and liquid crystal filter. The louver type filter generally has a plurality of fine louvers, each elongate direction of the louvers being aligned in the horizontal direction. However, in a first preferred embodiment, the elongate directions of the respective louvers are directed toward the driver's seat position, inclining through a predetermined angle at the driver's seat side of the louvers with respect to the horizontal direction of the vehicle. In a second preferred embodiment, a plurality of lamps are disposed on a peripheral position at the front passenger's seat position of the TV monitor screen. The substantially same effect as the first preferred embodiment can be achieved.
