摘要： A backlight (illumination device) (2) of the present invention includes a plurality of light sources (5) and a plurality of light guides (7, 17, . . . ) that allow light entered into the light guides from the plurality of light sources (5) to be emitted from surfaces of the plurality of light guides (7, 17 . . . ). Each of the light guides (7, 17, . . . ) includes: a light emitting section (7b, 17b, . . . ) that has a light emitting surface (7a); and a light guide section (7c) that guides, to the light emitting section (7b, 17b, . . . ), light entered into the light guides from the plurality of light sources (5). Each of the light guides (7, 17, . . . ) is also arranged such that the light emitting section (17b) of the light guide (17) that is adjacent to the light guide (7) overlaps the light guide section (7c) of the light guide (7). An edge surface (7e) of the light emitting section (17b) of the light guide (17) that overlaps the light guide (7) has concaved and/or convexed shape. The concaved and/or convexed shape serves as a light intensity adjusting section that reduces light transmission quantity.

摘要： A backlight (illumination device) 2 of the present invention includes light sources 5, optical guides 7 and 17 for causing a surface emission of light from the light sources 5, and a diffusing plate 8 for diffusing the light emitted via the optical guides 7 and 17. The diffusing plate 8 faces light-emitting surfaces of the optical guides 7 and 17, and is provided with a light-amount adjusting section 11 made from a transflective material and for causing a reduction in amount of light transmitted therethrough. The light-amount adjusting section 11 is provided to correspond to a region which causes a bright line due to the light from the light sources 5, i.e., so that its orthogonal projection to a light-emitting region defined by the light-emitting surfaces covers a boundary between the optical guides 7 and 17. By the above, an illumination device providing high luminance uniformity can be obtained.

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.
