摘要： An illumination device (30) includes a plurality of light source units (BLU) each having a light guide plate (1) and a plurality of light sources (21). The light guide plate (1) has an illumination region (4) through which incident beams of light from the light sources (21) are emitted outward and a light guide region (3) through which the incident beams of light from the light sources (21) are guided toward the illumination region (4), with the light guide region (3) and the illumination region (4) laid side-by-side. The illumination region (4) is divided into a plurality of light-emitting sections by slit sections (8), provided in such a way as to extend along directions of optical axes of the light sources (21), which restrict transmission of light. At least one of the light sources (21) is provided to each of the light-emitting sections in such a way as to be placed side-by-side along the light guide region (3). Light source units (20) adjacent to each other along the directions of the optical axes of the light sources (21) are disposed so that the illumination region (4) of one of the light source units (BLU) covers at least a part of the light guide region (3) of the other light source unit (BLU). This makes it possible to retain the strength of the illumination device as a combination of light guide blocks while reducing leakage of light into an adjacent area.

摘要： A light emitting element (1) includes: a plurality of light emitting diodes [3 (R1, G11, . . . )] of two or more colors; and a light guide plate (4) for causing light from the respective plurality of light emitting diodes [3 (R1, G11, . . . )] to surface-emit. The light emitting diodes are provided along the light guide plate (4) in a given order. The light guide plate (4) includes: a color mixing section (5) for mixing colors of light from the respective plurality of light emitting diodes [3 (R1, G11, . . . )]; and a display section (6) for causing the light, which has been subjected to a color mixture by the color mixing section (5), to surface-emit. The plurality of light emitting diodes [3 (R1, G11, . . . )] decrease in their respective luminous intensities from a center toward ends of the light guide plate (4). This allows obtaining a well color-mixed white light source without being colored in a color of light emitted from a light emitting diode provided on a side end surface side of a light guide plate.

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 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.

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.
