On the side of a light outgoing surface (43) of a light guide plate (4), a resin frame (2) is arranged with at least one optical sheet (3) therebetween. A protruding section (25) facing an end surface (45) adjacent to the light outgoing surface of the light guide plate is arranged on the resin frame. The protruding section is elastically deformable to the side opposite to the light guide plate which the protruding section faces. Since the protruding section elastically deforms and absorbs the stretch quantity of the light guide plate, the light guide plate does not deform. Therefore, light guide plate deformation generated due to relative dimensional change of the light guide plate due to changes of temperature and humidity can be eliminated over a long period of time.
