Then, transparent passive reflector 10 is provided along the outer circumference of filter 9 and perpendicularly nearly to video screen 7, and its flank is colored in dark grey low in reflection coefficient to obtain video frame 3. Next, conventional easement video display part 2 is omitted and the upper and right and left sides of video screen 7 are supplied with illuminating light. In this case the illuminating light is supplied to at least the upper part of video screen 7, so that the sufficient sensory effect can be obtained.
