Abstract: A display device includes an image display device that includes an image display surface that emits light polarized in one direction and displays an image; and a superimposing display device that includes a transparent light guide plate that is provided overlapping the image display surface, transmits the light emitted from the image display device, and also has grooves constituting a pattern formed thereon, includes a light source that irradiates an end surface of the transparent light guide plate with light, and is switched between display and non-display of the pattern based on lighting and non-lighting of the light source. A polarization direction of the image display device and an extending direction of the grooves intersect at an angle range of 75° to 105°. Accordingly, the display device can ensure proper visibility.

Abstract: A radial line dial plate includes a synthetic resin dial plate and a shaft through-hole that is provided to the dial plate such that a rotation shaft of a meter unit penetrates therethrough. The dial plate is provided with a plurality of grooves that extend radially outward from an opening rim of the shaft through-hole to form a radial line pattern provided on the dial plate, and the plurality of grooves are provided radially around a position different from a center axis of the shaft through-hole. Thus, there are provided a radial line dial plate and an automobile meter provided with the radial line dial plate in which the radial line pattern of appearance with comfortable and natural feeling as a metallic-tone dial plate can be stably given.

Abstract: A display device includes a first display surface displaying vehicle information; and a second display surface which is disposed facing the first display surface and transmits light, has a drawing pattern drawn across a display area and outside the display area of the first display surface when seen from a direction in which the second display surface is stacked on the first display surface, and can switch to a displayed state in which the drawing pattern is displayed and a hidden state in which the drawing pattern is hidden. The display device displays information by the first display surface and the second display surface. The display device can therefore realize a visual effect that makes the display area look relatively large.

Abstract: A metallic decorative part for a vehicle display device includes a substrate body molded from a synthetic resin, a metal thin film that is formed of metal and deposited on a surface of the substrate body, and a plurality of grooves deposited on a surface of the metal thin film in accordance with a shape of the surface of the substrate body. The grooves are formed so that a width is larger than 0 and equal to or smaller than 3.0 ?m, and a height is larger than 0 and equal to or smaller than 1.0 ?m. Accordingly, the metallic decorative part for a vehicle display device can properly secure a metallic texture recognized by a viewer with a configuration in which the metal thin film is deposited on the surface of the substrate body made of resin.

Abstract: A radial line dial plate includes: a substrate body made of resin on which a radial line mark region is molded by a die mark-molding-face of a molding die; a plurality of fine grooves that extend radially outward in a radial direction from a center of the radial line mark region without intersecting with each other and are formed such that a distance therebetween is 1 ?m or less at an outermost peripheral end to give a radial line pattern to the radial line mark region; and a metal thin film that is deposited to at least the radial line mark region of the substrate body.
