<P>PROBLEM TO BE SOLVED: To provide a lighting apparatus capable of downsizing with a simple structure, thereby suppressing the increase in manufacturing costs, and of securely keeping the gap between a light source and a light guide plate with high precision. <P>SOLUTION: A lighting apparatus 10 of this invention is characterized by having a light source 11 comprising a light emitting surface, a light source substrate 12 on which the light source is mounted in a posture that an opposite side of the light emitting surface is turned to a mounting surface and a light incident plane oppositely arranged to the light source on a part of an end face, and a light guide plate 13 which exits emitting lights of the light source entered from the light incident plane from a light exit surface formed on a plate face of one side. The device is also characterized in that a recess part 13x is formed on a part of the end face of the light guide plate, an inner face of the recess part is a light incident plane 13a, an end face part 13y other than the recess part of the end face on the side where the recess part of the light guide plate is formed is directly held toward a mounting surface 12a of the light source substrate, and the light source is placed without contacting the light incident plane within the recess part. <P>COPYRIGHT: (C)2008,JPO&INPIT |
