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 object is to implement a narrowed picture-frame while suppressing the occurrence of light leakage and a reduction in luminance in an edge-light type backlight device. A backlight device is composed of LEDs (40); a side chassis (51) supporting a board having the LEDs (40) mounted thereon; a light guide plate (20) for allowing light emitted from the LEDs (40) to exit toward a liquid crystal panel in a planar manner; a reflection sheet (30) for allowing light traveling toward a back surface side within the light guide plate (20) to be reflected thereby; optical sheets (10) including a reflection type polarizer (11), a prism sheet (12), and a diffuser (13); and a top chassis (52) disposed on top of the optical sheets (10). Black printing (60) is provided in a part of the region of the diffuser (13). A length of the reflection type polarizer (11) is longer than a length of the light guide plate (20) such that an edge of the reflection type polarizer (11) is located closer to a side of the LEDs (40) than is an edge surface of the light guide plate (20).

摘要： A large liquid crystal display (100) comprises a light guide plate (3) arranged on the back side of a liquid crystal panel (1). The front surface of the light guide plate (3) is flat, while the back surface thereof is concave. The upper and lower end faces of the light guide plate (3) respectively facing hot cathode fluorescent lamps (2a, 2b) have a convex shape projecting toward the respective lamps. White light from the fluorescent lamps is incident on the upper and lower end faces of the light guide plate directly or by being reflected by reflectors (4a, 4b), and propagates within the light guide plate while being reflected by the front and back surfaces of the light guide plate. At the front surface of the light guide plate, a part of the white light is directed toward the back side of the liquid crystal panel (1) by a light guide portion (5).

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.
