Zusammenfassung:	The utility model provides a face-shaped light source device which comprises a plurality of point-shaped light sources and a light guiding plate. Light from the point-shaped light sources is emitted in from an incident plane and is emitted out from an emitting-out face of the light guiding plate, an irradiated objected is irradiated, the light guiding plate is in the shape that two corners of one side face of a rectangular plate are cut off, the side face is a side face in the length direction of the light guiding plate, and two end portions formed after the two corners are cut off are provided with oblique faces which are oblique relative to the appearance of the light guiding plate, perpendicular lines which pass through any points on the two end portions and are perpendicular to the oblique faces, and top points which penetrate through the light guiding plate and are placed on the opposite-angle positions opposite to the oblique faces respectively. According to the face-shaped light source device, the even
