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 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.
