摘要： A light-emitting element (1) includes a plurality of light-emitting diodes [3(R1, G11, . . . )] of two or more different colors, and a light-guiding member (4) for emitting, in the form of plane emission, light emitted by the plurality of light-emitting diodes [3(R1, G11, . . . )]. The plurality of light-emitting diodes are arranged in a predetermined order along the light-guiding member (4). A scattering member (31) for scattering light is provided on that side surface of the light-guiding member (4) which faces in a width direction (i.e., a direction along the direction that the light-emitting diodes (3) are arranged). Thus obtained is a white light source, free from coloration attributed to the color of a light-emitting diode disposed next to a side edge surface, whose colors have been sufficiently mixed.

摘要： A control circuit changes the ratio of an illumination period to a non-illumination period in a frame period of a backlight according to a gradation level in the one frame period of an image displayed on a liquid crystal panel in such a manner that the higher the gradation level, the backlight illumination control circuit increases the ratio of the illumination period to the non-illumination period in the frame period of the backlight, and the lower the gradation level, the backlight illumination control circuit decreases the ratio of the illumination period to the non-illumination period in the frame period of the backlight and thereby controls illumination intensity toward the liquid crystal panel. A time center of illumination intensity in each one frame period of the backlight is controlled in order that the time center exists in a constant temporal position from the beginning of each frame period.

摘要： A backlight (illuminating device) of the present invention is a tandem type backlight including a plurality of light-emitting units (11) including at least one point light source (5) and a light guide plate (7) for causing light from the at least one point light source to be diffused and surface-emitted. In each of the light-emitting units (11), a length X of a light guide area (9) is set so that an area, on a boundary surface between a light-emitting area (10) and the light guide area (9), of a cross-section of a light beam that is emitted from the at least one point light source (5) and is diffused in the light guide plate (7) is equal to or larger than an area of the boundary surface (interface). Moreover, a length X, in a length direction D1, of the light guide area is smaller than a length Y, in the length direction D1, of the light-emitting area, the length direction being a direction pointing from the at least one point light source (5) toward the light-emitting area (10). With this, it is possible to realize an illuminating device in which light from a light source can be more uniformly emitted, and an increase in thickness of the illuminating device can be suppressed.

摘要： The present invention achieves a light guide unit capable of, with use of minimum-sized reflection means, (i) preventing light from directly leaking out from a light guide through a surface of the light guide and thus preventing luminance unevenness, and also (ii) suppressing an increase in production costs. Specifically, reflection means (8) is provided on an upper surface of a light guide part (2a) so as to cause light entered a light guide (2) to travel toward inside of the light guide (2). The reflection means (8) extends from one intersection (P) of first intersections so as to cover a region, of the upper surface of the light guide part (2a), which faces a light incidence surface (9) right above a light source (6). Each of the first intersections is an intersection of (i) a straight line extending at an angle θ to a vertical line (M) and passing through a second intersection and (ii) the upper surface of the light guide part (2a). The one intersection (P) of the first intersections is furthermost from the light source (6) among the first intersections. The vertical line (M) extends from an edge, of the light source (6), which is closest to the light emitting surface (2c) toward the light incidence surface (9). The second intersection is an intersection at which the light incidence surface (9) and the vertical line (M) intersect.

摘要： A liquid crystal display device (1) of the present invention includes a display panel (3) and a backlight (2) (an illumination device). The backlight (2) includes a light-emitting layer (20) in which a plurality of light sources (5) are scattered and a diffuser (7) (a diffusion layer) that is formed on the light-emitting layer and diffuses light from the light-emitting layer. The light sources (5) that are present within the light-emitting layer (20) emit light in a direction (a direction of an arrow) substantially parallel to a boundary surface between the light-emitting layer (20) and the diffuser (7). In the diffuser (7), a transmittance of light in an area (7c) close to each of the light sources is smaller than a transmittance of light in an area that is far from each of the light sources.
