Abstract

A video projection device such as a television receiver includes a cabinet (36) having front and rear sections and a projection tube (30) for projecting a video image. A screen (32) is located in the front section of the cabinet and has a first surface onto which the video image is projected and a second surface for displaying the video image so that it is observable by a viewer. A mirror (35) is arranged in the cabinet for reflecting light to the first surface of the screen. The projection tube is rearwardly facing for projecting the video image onto the mirror.
