Claim Text:
1. An illumination device, comprising: a plate member; a light guide plate having a side face acting as a light-receiving face, the light guide plate being disposed such that a surface thereof faces a surface of the plate member; a light source disposed above said surface of the plate member so as to face the light-receiving face; a reflective sheet disposed so as to be in contact with said surface of the light guide plate; a buffer member disposed on said surface of the plate member to support the reflective sheet in a position that is directly below the surface of the light guide plate that faces said surface of the plate member and that is horizontally separated from said light-receiving face of the light guide plate, the buffer member supporting the reflective sheet such that an edge portion of the reflective sheet adjacent to said light receiving face of the light guide plate is not fixed to said surface of the light guide plate, thereby allowing the edge portion to be detached from said surface of the plate member; and a protruding member that protrudes from said surface of the plate member between the light source and the light-receiving face, the protruding member having a height greater than a height of said surface of the light guide plate, the protruding member blocking light from the light source directed towards said edge portion of the reflective sheet that is detached from said surface of the light guide plate.
