    摘要: A liquid crystal display device which can make the surface brightness of an edge-light-type backlight uniform is provided. The liquid crystal display device includes a liquid crystal display panel and a backlight which radiates light to the liquid crystal display panel. The backlight includes a light guide plate which is arranged on a back side of the liquid crystal display panel, a light source arranged on an outer peripheral portion of a first main surface of the light guide plate which faces the liquid crystal display panel in an opposed manner, and a reflection sheet which is arranged on a back side of the light guide plate as viewed from the liquid crystal display panel. The light guide plate is made of a transparent resin having a refractive index of 1.53 or less. On a surface of the light guide plate opposite to the first main surface, a second main surface which is substantially parallel to the first main surface and a plurality of inclined surfaces which are inclined at a preset angle with respect to the second main surface are formed. An angle of the inclined surface positioned near a position at which light from the light source is incident and an angle of the inclined surface positioned remote from the position at which the light from the light source from the light source is incident differ from each other.

    摘要: Provided is a display device including: a light guide plate arranged so that an edge surface thereof is opposed to a light source, the light guide plate being configured to internally reflect light entering from the edge surface to cause planar light emission from a front surface of the light guide plate; and a reflective sheet arranged so as to be opposed to a rear surface of the light guide plate. Irregularities are formed on the front surface. The irregularities are formed to have a shape of a combination of first convex portions and second convex portions, each of the first convex portions including a first ridge line which continuously extends along a first direction corresponding to a light traveling direction, each of the second convex portions including a second ridge line which continuously extends along a second direction intersecting the first direction.

    摘要: A liquid crystal display device includes a display panel, a backlight which radiates light to the display panel, a light emitting element which is mounted on the backlight, and a light guide plate on which light from the light emitting element is incident. The light guide plate has an upper surface and a bottom surface. The bottom surface has grooves formed therein delimited by at least one surface which extends at a slant with respect to the bottom surface. A reflection sheet is provided which reflects the light radiated from the bottom surface. The grooves are formed to produce a first light which is reflected on the grooves and a second light which is radiated from the grooves and is reflected on the reflection sheet, and an asymmetric prism sheet is arranged on the light guide plate.

    摘要: A lightguide to be used in a liquid crystal display device includes a light exit surface, a reflection surface opposed to the light exit surface, and a light entrance surface, which is one side surface. In a region of the light exit surface or the reflection surface, which is on a front side of an intermediate portion between two light sources when viewed from the light entrance surface, a plurality of local-area line-shaped protrusions are arranged, which are extending in a first direction. Each of the local-area line-shaped protrusions reflects the entered light so that a component of the entered light which is orthogonal to the first direction is weakened. A length of a local-area line-shaped protrusion farthest from the two adjacent light sources, is larger than a length of a local-area line-shaped protrusion closest to any one of the two adjacent light sources.
