摘要： A light guide plate is formed of a light introducing part positioned to face a point light source for confining light and a light guide plate body having a thickness smaller than the thickness of an end of the light introducing part on a point light source side and causing the confined light to be output from a light exit surface to outside. The light introducing part has an inclined surface, and a directivity conversion pattern formed on the inclined surface. The directivity conversion pattern is configured by arranging V grooves in parallel to each other, each having a vertical angle of 120°, and each extends in a direction approximately perpendicular to a light incidence end face of the light guide plate. The length of the inclined surface in a inclination direction where part of light incident to the light introducing part enters the inclined surface at least twice.

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.
