LIGHT SOURCE DEVICE, AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light source device capable of fixing a light emitting module and a heat sink to each other, while preventing occurrence of unevenness in luminance and color due to unevenness of a degree of adhesion between them.SOLUTION: The light source device includes: a light emitting module 110 in which a plurality of LED elements 112 are arrayed on a base board 111 in the longitudinal direction of the base board 111; the heat sink 130; a first hook portion 142c which locally locks one of both edges of the light emitting module 110 in a short direction thereof with a claw 142e in a state of pushing the base board 111 to the heat sink 130 side; and a second hook portion 143c which locally locks the another of both the edges with a claw 143e. The claws 142e and 143e are disposed zigzag to be displaced from positions facing each other in the longitudinal direction.
