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： 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.
