Abstract: A laminated glass has a vehicle exterior side glass plate; a vehicle interior side glass plate; and an intermediate film disposed between the vehicle exterior side glass plate and the vehicle interior side glass plate. The laminated glass includes a display area for reflecting a projected image projected from vehicle interior, to display information. In at least a part of the display area, a film is arranged between the vehicle exterior side glass plate and the vehicle interior side glass plate. The film is a main reflection surface for the projected image. The display area is offset from the edge of the film by 5 mm.

Abstract: To provide a reflective transparent screen exhibiting high brightness over a wide region in the screen although with a narrow viewing angle, and an image display system.
A reflective transparent screen comprising:
a first transparent layer 32 having an irregular surface,
a reflective layer 40 formed on the irregular surface, and
a second transparent layer 52 formed on the irregular surface on which the reflective layer 40 is formed, so as to fill irregularities,
the irregular surface of the first transparent layer 32 having a slant angle in a first direction being within a range of from −44° to +44°, and a slant angle in a second direction perpendicular to the first direction being within a range of from −44° to +44°.

Abstract: There is provided a transparent screen which is capable of separating a direction where a hot spot is observed and a direction where a bright video is allowed to be observed, and establishing a direction where a video is allowed to be wholly brightly observed.A transparent screen includes a first transparent layer, a reflective layer reflecting projected video light, a second transparent layer disposed opposite to the first transparent layer with respect to the reflective layer so as to make a background visible therethrough; wherein the reflective layer has a plurality of slant reflective surfaces, each of the slant reflective surfaces being slant to a reference surface that is a surface of the first transparent layer opposite to the reflective layer; wherein each of the slant reflective surfaces is provided with a concavo-convex and is formed in a stripe shape when seen from a normal direction of the reference surface; and wherein the slant reflective surfaces are disposed so as to have angles to the reference surface, the angle changing with random variations in of range with respect to a certain central angle.

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°.
