摘要： A thin flat-surface type display device having a transmissive display panel is provided, which is capable of securing a space of an essential electric circuit for driving the display device without deteriorating an optical performance (luminance and uniformity thereof) of a surface light source device of an edge light system employed as a backlight. A light guide plate forming the surface light source device of the edge light system has a flat light emitting surface, and a back surface arranged so as to include (1) an inclined flat surface portion where a thickness of the light guide plate decreases linearly from a light-incident portion on which light emitted from a linear light source is incident toward a light-anti-incident portion, and (2) a parallel flat surface portion which is parallel with the light emitting surface in the vicinity of the light-anti-incident portion. Also, the two adjacent surfaces are connected to each other at an interface portion with an interface curved surface such that makes the two adjacent surfaces tangential. In addition, reflection dots are formed at the back surface side of the light guide plate in a predetermined shape at a predetermined density.

摘要： In order to prevent the display quality of a display device from deteriorating due to an external stress, a liquid crystal panel for displaying images and characters, and an illuminator for projecting light from the back of the liquid crystal panel are supported by a mold frame (1) in FIG. 3 and a front frame fixed to the mold frame (1). The mold frame (1) is formed with mounting holes for attaching the liquid crystal panel to an external device such as personal computer, and is at its corners with cutouts (20) for absorbing the external stresses which are propagated through the mounting holes in a state where the display device is attached to the external device.

摘要： A liquid crystal display device comprising a liquid crystal display panel and a light guide plate arranged in a rear side of the liquid crystal display panel. The liquid crystal display panel is of a substantially spherical shape, and the liquid crystal display panel is fitted at a front side of the light guide plate such that a proximity of a central portion of the liquid crystal display panel is outwardly bulged. There can be prevented display deficiencies (paddling) owing to interference between the liquid crystal display panel and the backlighting unit or between the former and the casing. Moreover, since no interference exists between the liquid crystal display panel and the backlighting unit or between the former and the casing, sheets such as the diffusing sheet will not be wrinkled, and the brightness of the backlighting unit can be maintained to be uniform.

摘要： A prism member is interposed between an LED board and a light incidence surface of a light guide plate. The prism member includes a prism sheet consisting of minute prisms that are arranged along the LED board and that have a function of refracting light that is emitted from each LED and thereby inputting, to the light incidence surface, refracted light that is scattered to both sides in the longitudinal direction of the light incidence surface. As a result, chrominance or luminance unevenness can be prevented even if the distance between the LED board and the light incidence surface is short.
