Abstract: An illumination device of the present invention is provided with: a light source; a light guide plate having a light-receiving face that faces the light source and on which light that has been generated from the light source is incident, an opposite surface that is on the opposite side to the light-receiving face, and a light-exiting surface from which light that has entered the light guide plate from the light-receiving face exits; a first wall disposed along the front-back direction of the light guide plate and having a light absorbing surface that faces the opposite surface and absorbs light that has leaked out from the light guide plate; and a first light absorbing member that extends between a front periphery adjacent to the opposite surface on the light-exiting surface and a front end of the first wall, and absorbs light that has leaked out from the light guide plate.

Abstract: The present invention provides an illumination device that is provided with: a flexible substrate having an overlapping portion that contacts the light-receiving face side of the light-exiting surface of a light guide plate and in which substrate recesses and substrate protrusions are formed; a plurality of side-illumination type LEDs mounted in a line on the flexible substrate, with the LEDs facing the substrate recesses and the spaces between adjacent LEDs facing the substrate protrusions; first light-incident portions provided in positions that overlap the interior regions of the substrate recesses and at which light, having been emitted from the LEDs towards the portions of the light-receiving face that face the LEDs, arrives; and second light-incident portions that have a higher optical reflectance than the first light-incident portions and are provided on a surface that faces the LED-side of the substrate protrusions and at which light, having been emitted from the LEDs towards the portions of the light

Abstract: An optical sheet (optical member) includes: a sheet-shaped base material 40 that is light-transmissive; an anisotropic light condenser that is formed on the light-receiving surface of the base material where light is received, the anisotropic light condenser having light condensing anisotropy such that incident light is condensed in a light condensing direction along the light-receiving surface whereas light is not condensed in a non-light condensing direction along the light-receiving surface, the non-light condensing direction being perpendicular to the light condensing direction; and an anisotropic light scatterer that is formed on the light-emitting surface from which light is emitted, the light-emitting surface being on a side of the base material opposite to the light-receiving surface of the base member, the anisotropic light scatterer scattering and emitting light from the anisotropic light condenser, and having light scattering anisotropy where light is greatly scattered in the light condensing direc

Abstract: A liquid crystal display device is provided with: a liquid crystal display panel (120); a front bezel (110) located on the display surface side of the liquid crystal display panel (120) and having an opening (111) in the side wall thereof; and a rear bezel (132) located on a side of the liquid crystal display panel (120) opposite to the display surface side and having on the sidewall thereof a tab (131) engaging the opening (111). The liquid crystal display device is also provided with an elastic body (140) that is located between the front bezel (110) and the rear bezel (131) and that, in a state in which the opening (111) and the tab (131) engage each other, pushes the front bezel (110) and the rear bezel (132) in the respective directions further away from each other. The elastic body (140) is made of a plurality of elastic members (141, 142) that have different elastic moduli.

Abstract: The present invention aims to provide a display device that allows suppression of occurrence of Newton's rings while allowing reduction in number of required components. The display device of the present invention includes an optical unit including a first main surface, a peripheral surface—and a second main surface disposed to face the first main surface; a display panel and a reflective sheet including a first main plane portion covering the first main surface, a peripheral surface portion covering the peripheral surface, and a second main plane portion extending from the end portion of the peripheral surface portion and located on the second main surface. The display panel is disposed at a distance from the optical unit by sandwiching the second main plane portion between the display panel and the optical unit.

Abstract: Disclosed is a display device facilitating reduced assembly time and disassembly time. In a liquid-crystal display device, protrusion parts and hook parts are disposed upon a frame. On a front side bezel are disposed notch parts wherein the protrusion parts are hooked, and hook holes wherein the hook parts are hooked by the protrusion parts being slid along the notch parts. On a rear side bezel are disposed notch parts wherein the protrusion parts are hooked, and hook holes wherein the hook parts are hooked by the protrusion parts being slid along the notch parts. The hook holes have a function of restricting movement of the hook parts in the B1 direction.

Abstract: A twin-hull boat equipped with a pair of transverse hydrofoils 4 and 5 which are respectively secured to the bottom surface of twin-hull structures 3A and 3B adjacent the stem and stern. A pair of auxiliary wings 6A and 6B are installed opposite to each other at predetermined positions on the internal wall surfaces of the twin-hull structures 3A and 3B mutually facing the hull center line and at a predetermined height between the upper water line formed in the course of low-speed cruising and the lower water line formed in the course of high-speed cruising. The twin-hull boat incorporates a postural angle regulating device 15 to properly regulate the postural angle of the auxiliary wings 6A and 6B by causing them to pivot about a horizontal axis.
