Abstract: To provide an image projecting structure having a wide viewing angle and whereby the visibility of a projected image is high. The image projecting structure comprises a first transparent layer having irregularities formed on its surface, a reflective film formed on the surface on which the irregularities are formed, of the first transparent layer, and a second transparent layer formed on the reflective film, wherein the transmittance of visible light is from 5 to 95%; the value obtained by dividing the haze by the diffuse reflectance of visible light is at least 0.1 and at most 1; the vertical difference Sk in the core section defined by ISO 25178, of the surface on which the irregularities are formed, is at least 0.1 μm; and the value obtained by dividing the shortest autocorrelation length Sal by the vertical difference Sk in the core section is at least 1.2 and at most 190.

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 transparent screen includes a plurality of transparent plates arranged in a front-rear direction; and a screen main body, interposed between the transparent plates, configured to display video images projected from a front side or a rear side of the transparent screen to a user on the front side, and enable a rear background to be visually recognized by the user. In a cross section orthogonal to a part of an outer edge of the transparent screen, the transparent screen has a curved shape, and a length of a center line in a plate thickness direction of the transparent plate on an external side of the screen main body in a curvature radius direction of the curved shape is greater than a length of a center line of the transparent plate on an internal side of the screen main body.

Abstract: A vehicular laminated glass in which a plurality of glass plates and an intermediate film disposed between the plurality of glass plates are stacked. The vehicular laminated glass includes a first region having a colored layer disposed along an upper edge of the vehicular laminated glass with reference to an orientation of a vehicle to which the vehicular laminated glass is attached, and a second region disposed lower than the first region. The first region includes a region A having a light scattering layer and a region B not having the light scattering layer. In the region A, a visible light transmittance is 0.7% to 32%, a visible light reflectance is 0.5% to 10%, a vehicle-inner side visible light diffuse reflectance is 3% to 45%, and the light scattering layer is arranged at a vehicle-inner side relative to the colored layer.
