<p>PROBLEM TO BE SOLVED: To provide a light source device wherein screen illumination and color unevenness defects are prevented by preventing peeling-off of a reflecting membrane generated by a load accompanied, when a feeder line junction is mounted on a concave reflecting mirror inner surface. SOLUTION: In the light source device, having a discharge lamp of a both-ends sealing type where a pair of electrodes are oppositely placed in a light-emitting tube and having the concave face reflecting mirror wherein a reflecting coating film is formed on the inner surface, wherein a sealing part of one side of the discharge lamp is inserted into and fixed to a neck part opening of the concave face reflecting mirror, and wherein the feeder line joined to an outer lead drawn out from the other side of the sealing part of the discharge lamp is inserted into and penetrated through a pinhole part penetrated and formed in a curved surface part of the concave face reflecting mirror through the inside of a metallic cylindrical tube with a flange penetrated through the pinhole part, so as to be joined to a metal terminal at a rear side surface of the concave face reflecting mirror, a buffer member is arranged between the opening circumferential domain of the concave reflecting mirror inner surface side of the pinhole part and the flange of the metal cylindrical tube with the flange.</p> |
