Abstract

PURPOSE: To widen a supervisory area with the area of a video screen which can be supervised enlarged by arranging an easement optical system which approaches the same plane as the video screen at a position away from the outer circumference of the video screen.
CONSTITUTION: Transparent type scattering plate 6 in a frame shape encircling the outside of video screen 2 of color picture tube 1 is implanted perpendicularly to video screen 2. Neutral filter 7 is mounted on this transparent type scattering plate 6 and then fixed. Transparent type scattering plate 8 is provided forming the same plane as neutral filter 7. Shapes of the scattering surfaces of transparent type scattering plates 6 and 8 are so employed that rransmitting light can be scattered holding its directivity to a certain degree. Light absorption part 9 is provided to the back position of transparent type scattering plate 8 nearly in parallel to it. The width of light absorption part 9 is made less than that of transparent type scattering plate 8 and then, reflection part 10 is provided between terminals at the outer sides of the both.
