摘要： An area light source device has a diffusion plate and a prism sheet stacked on a light guide plate, and a light source disposed opposite an end face of the light guide plate. Light emitted from the light source is introduced to an inside of the light guide plate from the end face. Area light emission is obtained by outputting the light diffused in the light guide plate from the diffusion plate and the prism sheet through a front face disposed opposite the diffusion plate. The light guide plate includes a light guide section that includes the end face disposed opposite the light source, a light emitting section that is disposed opposite the diffusion plate, and a joining section that joins the light guide section and the light emitting section. The front surface in the joining section includes an inclined surface that is gradually retreated toward a rear surface on an opposite side from the light guide section toward the light emitting section. The front faces of the light guide section and the joining section are covered with a light shielding member. The light shielding member is fixed to the diffusion plate without interposing the prism sheet therebetween. The light shielding member and the inclined surface are arranged to allow air to be interposed therebetween.

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.
