摘要： Provided is an illumination device for obtaining planar light having satisfactory uniformity and suppressed brightness irregularities. A backlight unit (illumination device) (20) comprises a light source and a light-guiding element (23) for guiding light from the light source. The light-guiding element (23) includes prisms (23q) formed in an end area (22b) on the light source side, and prisms (23i) formed in an area (a light-emitting area (22a)) on the side opposite the light source relative to the end area (22b). The prisms (23q) vary the propagation angle of light spreading in a direction intersecting the direction of light entry, more so than the prisms (23i).

摘要： A backlight unit comprises a light source, a light guide plate and a frame. The light guide plate comprises a light guide and a low-refractive-index layer. The refractive index of the low-refractive-index layer is less than the refractive index of the light guide. A plurality of prisms for gradually reducing the angle of incidence of light coming from the light source with respect to the rear surface of the light guide are provided to the front surface or rear surface of the light guide. A plurality of prisms for totally reflecting forward the light coming from the light source are provided to the rear surface of the light guide plate. The frame comprises walls for surrounding the light source and the light guide plate. The width of the upper side of the walls and the width of the lower side thereof are substantially equal.
