Abstract

PURPOSE: To eliminate adverse influence owing to flare light, make external light reflection much less and achieve higher contrast by forming the specified light absorptive pattern on the screen formed with fine unevenness.
CONSTITUTION: A grating pattern 7 formed by light absorbing material is provided in provided in the surface 4a of a transmission type screen 4 which is formed with a transparent plate 6 provided with fine unevenness and the vertical and horizontal pitches of the pattern 7 are made smaller than one picture element and are virtually undiscernible. If TV images, etc. are back-magnification-projected by using this screen 4, the flare light transmitted along the inner side of the face 4a by the pattern 7 is cut off and the quantity of reflection of external light is reduced, thus the increase in contrast may be achieved.
