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： A liquid crystal display panel formed by using a TFT substrate and a color filter substrate is polished to decrease the thickness thereof so that it can be curved. The liquid crystal display panel and various optical sheets are sandwiched between a frame forming a curved surface and a light guide plate forming a curved surface, to thereby form a curved surface. An upper polarizer plate and a lower polarizer plate are, respectively, sandwiched between the surface cover and the liquid crystal display panel, and between the liquid crystal display panel and the optical sheet, and are not adhered or are partly adhered to the liquid crystal display panel.

摘要： A liquid crystal display panel includes a TFT substrate and a color filter substrate respectively formed of a glass substrate. By housing the liquid crystal display panel in the inside of a frame having a curved surface, a predetermined curved surface is imparted to a display screen. Using a direct backlight having a plurality of fluorescent lamps, distances between the respective fluorescent lamps and the liquid crystal display panel are set to a fixed value. A diffusion plate has a curved surface substantially equal to the display screen. By mounting respective optical sheets on the diffusion plate, predetermined curved surfaces are imparted to the respective optical sheets. Due to such constitution, it is possible to realize a liquid crystal display device having a curved surface without using a complicated optical system.
