摘要： A point-light-source type light emitting portion faces a light incident face located at a corner portion of a light guide plate. A light diffusion pattern for emitting the light in the light guide plate from a light emission face is on the lower surface of the light guide plate. A diffusion prism sheet is on the light emission face. A prism sheet including prisms each having a concentric shape with the light emitting portion at the center is on the lower surface of the diffusion prism sheet, and an uneven diffusion plate is on the upper surface of the diffusion prism sheet. Light emitted from the light emission face of the light guide plate along the light emission face is deflected in the direction perpendicular to the light guide plate by the prism sheet, and the angle of beam spread of the light is spread by the uneven diffusion plate.

摘要： On a light guide plate (32), a prism sheet (36), an uneven diffuser plate (37) and a correcting optical sheet (38) are placed one over another. Light outputted from the light guide plate (32) in a direction substantially parallel to a light outputting surface (45) is bent to a direction substantially vertical to the light outputting surface (45) by the prism sheet (36). Light which passed through the prism sheet (36) and has a long directivity characteristic in an r axis direction is converted into light having a substantially circular directivity characteristic by passing through the uneven diffuser plate (37). Furthermore, the light which passed through the uneven diffuser plate (37) and has the substantially circular directivity characteristic is converted into light having a directivity characteristic closer to a perfect circle by the correcting optical sheet (38). The correcting optical sheet (38) is formed of a pattern having many polyhedron shapes.

摘要： A protecting sheet 112 having a transparent rubber-like resin 113 formed on a transparent board 114 is interposed between a light emitting plane 123 of a light guiding plate 111 and a surface, at which prisms 116 are formed, of a prism sheet 115 in such a manner that the transparent rubber-like resin 113 is brought into contact with vertexes of the prisms 116. The transparent rubber-like resin 113 holds the prism sheet without any deformation without any application of external force, thus preventing any occurrence of an optical close contact between the prism sheet 115 and the protecting sheet 112. In contrast, the transparent rubber-like resin 113 is deformed with the application of the external force, thus preventing any breakage of the prism 116.
摘要翻译：在透明板114上形成有透明橡胶状树脂113的保护片112插入在导光板111的发光平面123和形成有棱镜116的表面之间，棱镜片115在其上形成透明橡胶状树脂113与棱镜116的顶点接触的方式。透明橡胶状树脂113在不施加外力的情况下保持棱镜片没有变形，从而防止棱镜片115与保护片112之间的光学紧密接触的发生。相反，透明橡胶状树脂113随着外力的变形而变形，从而防止了棱镜116的任何破损。

摘要： A light guide plate has a light incident surface arranged facing a plurality of point light sources arrayed in a line, a light exit surface orthogonal to the light incident surface, and two side surfaces orthogonal to the light incident surface and the light exit surface. Light from the plurality of point light sources introduced from the light incident surface is diffused by a diffusion unit arranged on the light exit surface or a surface facing the light exit surface. The light diffused by the diffusion unit is exited from the light exit surface. A distance between a point light source positioned at an end of the plurality of point light sources and the light incident surface is different from a distance between a point light source not positioned at the end of the plurality of point light sources and the light incident surface.
