摘要： An area lighting unit has an electroluminescent device, a light scattering portion on a side of a light exit surface of the electroluminescent device, and a light covering portion on a side of a light exit surface of the light scattering portion. The light converging portion includes first and second layered optical sheets, each having a planar light incidence portion through which light enters and a light exit portion through which the light exits. The light exit portion of each optical sheet forms parallel prismatic protrusions, each having a vertex angle of 90 degrees to 105 degrees. The optical sheets each are so arranged that the light incidence portion is oriented to the electroluminescent device and a direction in which the protrusions of the first optical sheet are arranged is perpendicular to a direction in which the protrusions of the second optical sheet are arranged.

摘要： After entering a transparent substrate 9 of an organic EL device and passing through this substrate 9, an outside light L1 further passes through a transparent layer 10, a transparent electrode 12, and an organic light emitting layer 13 to be reflected by a reflective electrode 14. Herein, the reflective electrode 14 has irregularities and therefore the outside light L1 is diffused and reflected by this at various angles. These reflected lights are further diffused when passing through a boundary between the organic light emitting layer 13 and the transparent electrode 12 and through an irregularity surface 11 of the transparent layer 10, and outgo from the transparent substrate 9 toward a liquid crystal panel. On the other hand, lights L2 to L4 emitted from the organic light emitting layer 13 are diffused when passing through the boundary between the organic light emitting layer 13 and the transparent electrode 12 and through the irregularity surface 11 of the transparent layer 10, and outgo from the transparent substrate 9 toward the liquid crystal panel.

摘要： A light guiding plate guides light from a light source and irradiates the light onto a display portion. The light guiding plate has an incidence plane, which permits light to enter the light guiding plate, an opposite and plane opposite to the incidence plane an exit plane facing the display portion, and a reflection-exit plane opposite to the exit plane. A plurality of grooves are formed on the reflection exit plane. In any adjacent pair of the grooves, the depth of the groove closer to the opposite end plane is equal to or greater than the depth of the groove closer to the incidence plane. The depth of the grooves substantially increase from the incidence plane toward the opposite end plane. This improves the uniformity of brightness distribution.
