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.
