TITLE OF THE INVENTION TRANSMISSION-TYPE SCREEN AND VIDEO PROJECTION TELEVISION ABSTRACT OF THE DISCLOSURE A transmission-type video projection television system employs a transmission-type screen for displaying an image projected from a rear projector for visual observa- tion by an observer in front of the screen. The transmis- sion-type screen has Fresnel and lenticular lenses, one of which has an electrically conductive layer or a metal mem- ber on its surface to prevent the lens from being electro- statically charged, so that dust or dirt particles will not be attracted to the screen. - 30 -
