摘要： A semi-permeable/reflective sheet (19) has a lower surface as a flag light incident surface (47) and a surface opposite to the light incident surface (47) where a light reflection area (43a) and a light transmittance area (43b) are provided. The light transmittance area (43b) is a flat surface parallel to the light incident surface (47). The light reflection area (43a) is formed by a convex pattern (42) having a cross section of a rectangular equilateral triangular shape. A part of light (41) coming from the light incident surface (47) to the light transmittance area (43b) transmits the semi-permeable/reflective sheet (19) and goes out of the surface opposite to the light incident surface (47). A part of the remaining light (41) incident from the light incident surface (47) is reflected twice by reflection walls (44, 45) forming the convex pattern (42). The light reflected by the reflection walls (44, 45) is emitted in parallel to the previous incident direction and in the reverse direction to the incident light.

摘要： A plane source of light (back light) of the type of emitting light from both surfaces featuring a good light utilization efficiency and without permitting the external light to transmit through a display device even when it is combined with display panels of the transmission type. Light is introduced from a point source of light into a light guide plate. Many deflecting patterns of a triangular shape in cross section are formed in a recessed manner in a surface (pattern surface) on the side opposite to a light-leaving surface of the light guide plate. A prism sheet forming a plurality of arcuate prisms is arranged on a position facing the pattern surface of the light guide plate. Light propagating through the light guide plate is totally reflected by the deflecting pattern and goes out from the light-leaving surface nearly perpendicularly thereto. Light propagating through the light guide plate transmits through the deflecting patterns, goes out aslant, and is bent by the prisms into a direction nearly perpendicular to the pattern surface as it transmits through the prism sheet.

摘要： Even when molded sagging is generated on a side of a pattern for diffusion, a light is made hard to be scattered in an irregular direction. In a state viewed from a direction perpendicular to a light conductive plate, a light is incident from a substantially fixed direction upon respective diffusion patterns 36 provided on a lower surface of the light conductive plate. A reflection surface 46a being an inclined surface of each of the diffusion patterns 36, which faces a light emission part, is formed to be trapezoidal in shape, and side surfaces 46b of the diffusion pattern 36, on which molded sagging is liable to be generated, hide behind the reflection surface 46a as viewed from a light source part, so that a light is hard to be made incident upon the side surfaces 46b.

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.
