Abstract: There are provided a video projecting structure, which is capable of having not only transparency but also high visibility of a video, a process for producing the same, and a video display system including the video projection structure.
A video projecting structure includes a first transparent layer having irregularities disposed on a surface thereof, a reflective layer disposed on the surface of the first transparent layer, and a second transparent layer disposed on the reflective layer; wherein when a surface of the first transparent layer opposite to the reflective layer is defined as a reference surface, the irregularities include a plurality of slant surfaces slant to the reference surface and reflecting light from a video; wherein when a first direction, a second direction and a third direction are defined such that the first direction is perpendicular to a normal direction of the reference surface, the slant surfaces extend in the first direction, the second direction is orthogonal to the first direction, the slant surfaces are arrayed in the second direction, and the third direction is a direction in which the slant surfaces have an average slant angle θ to the reference surface in section in the second direction; the irregularities include a portion which is configured such that when an average spacing Sm1 of the irregularities in the first direction, an average spacing Sm2 of the irregularities in the second direction and an average spacing Sm3 of the irregularities in the third direction are such that Sm2>Sm1 and Sm3>Sm1 are met, and Sm2 is maximum; and wherein the irregularities include a portion which is configured such that when a frequency distribution of inclinations of the irregularities in the second direction to the reference surface is measured in 0.25° divisions in every distance of 1 mm in order that the frequencies are represented as distances, the absolute value of a median value in the frequency distribution is a value other than 0°.

Abstract: A reflective transparent screen (1) capable of displaying an image light projected from a projector as an image to an observer who is on the same side as the projector, is provided with two transparent substrates and a metal thin film (23) sandwiched therebetween, wherein the color tone of the image light reflected from the metal thin film (23) or the image visibility is improved by adjusting the metallic composition of the metal thin film (23).
