ABSTRACT:
A planar illumination device comprises a light guide plate, a point-like light source arranged on an incoming-light face of the light guide plate, an inner frame formed substantially in a U-shape on a top view, and an outer frame having a seat portion and side walls wherein the light guide plate is accommodated in the inner frame and mounted on the seat portion of the outer frame, while the point-like light source is arranged along the incoming-light face of the light guide plate and held between the incoming-light face and the side wall of the outer frame. At the inner frame, an elastic action portion which is elastically deformed so as to make a partial contact with the outer frame and energizes the light guide plate toward the point-like light source is provided.
