摘要： To make an efficiency of utilizing light with high efficiency in a plane light source apparatus used along with a liquid crystal display panel of a reflection type as a backlight, light f3 leaked from a rear face of a light guide plate 25 in a skewed direction, is incident on inside of a prism sheet 27 and reflected by a reflecting face 32. Light f3 reflected by the reflecting face 32, is reflected in a direction orthogonal to the prism sheet 27, passes the light guide plate 25 and is emitted from a light emitting face 30 of the light guide plate 25 in a direction orthogonally thereto.

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.
