    • A lighting unit of the present invention includes a light guiding plate (3), a light source (2) disposed so as to face an end face of the light guiding plate, a reflector (4) disposed so as to surround the light source, a housing (6) disposed so as to have a light guiding plate-retaining portion (6a) that retains at least the reflector and is partially interposed between the light source and the end face of the light guiding plate so as to retain the light guiding plate, and a reflecting sheet (5) disposed on one of principal surfaces of the light guiding plate, the lighting unit being configured such that light from the light source enter into the end face of the light guiding plate and goes out from another principal surface of the light guiding plate. The reflecting sheet is disposed so that an edge portion (5a) is bent so as to be positioned between the light guiding plate-retaining portion of the housing and the end face of the light guiding plate.
    • 本发明的照明单元包括导光板(3),与导光板的端面对置地设置的光源(2),设置成围绕光源的反射器(4) 设置成具有保持至少所述反射器并且部分地插入在所述光源和所述导光板的端面之间的导光板保持部(6a)的壳体(6),以保持所述光 引导板和布置在导光板的一个主表面上的反射片(5),照明单元被配置为使得来自光源的光进入导光板的端面并从另一个主体 导光板的表面。 反射片被设置成使得边缘部分(5a)被弯曲,以便被定位在壳体的导光板保持部分和导光板的端面之间。
