Zusammenfassung: | PROBLEM TO BE SOLVED: To perceive a bright color having high saturation by constituting a stray light absorption layer on the surface of a screen of the aggregate array of respective color dots of cyan, magenta and yellow being three primary colors of subtractive color mixture which are mixed and distributed in the surface direction of the screen. SOLUTION: A light absorption layer 3 is provided on the surface of a white reflection layer 2 functioning as the surface of the screen laminated on the surface of a screen base 1. The screen is constituted of the aggregate array of the minute color dots C, M and Y of cyan, magenta and yellow being the three primary colors of the subtractive color mixture which are mixed and distributed to closely cover all the surface of the screen in the surface direction. Thus, the influence of stray light in an observation chamber is reduced in the same manner as the conventional middle gray screen, and also reflectance to the primary colors is kept higher than in the case of the conventional middle gray screen. In the case of observing a picture projected to the screen, an observer perceives the bright, color having the high saturation. |
