发明名称 Polarizing screen
摘要 A polarizing screen 20 for presenting images in response to receipt of imagewise rays of light 22 projected from, for example, a video projector. The polarizing screen 20 is made of a woven polarizing fabric 1 which has front and rear surfaces D and E opposite to each other and which is woven in a satin fashion including warps of one of polarizing and non-polarizing threads 12 and 11 and wefts of the other of the polarizing and non-polarizing threads 12 and 11. The front surface D of the woven polarizing fabric 1 has a relatively large portion of the polarizing threads 12 being exposed therefrom and the rear surface E thereof has a relatively large portion of the non-polarizing threads 11 exposed therefrom. The polarizing threads 12 of the woven polarizing fabric 1 have their lengthwise direction oriented substantially perpendicular to a horizontal plane and, therefore, the horizontal viewing angle is increased. Also, the front surface D of the woven polarizing fabric 1 where the relatively large portion of the polarizing threads 12 are exposed is oriented so as to confront the viewers 23 so that the woven polarizing fabric 1 can exhibit an enhanced function of a polarizing filter. <IMAGE>
