Abstract
A video display device includes a laser beam source module including a laser beam source emitting a laser beam and a laser beam source drive unit supplying power to the laser beam source, and an image generation unit generating a desired display image from the laser beam. The laser beam source module includes a substrate having the placed laser beam source and improved thermal conductivity, a temperature measurement member measuring a temperature of the substrate, a temperature adjustment member contacting the substrate and adjusting the temperature of the substrate, a circuit substrate electrically connecting the temperature measurement member and the laser beam source. Moreover, the circuit substrate is disposed on a rear surface opposite to a placement surface on which the laser beam source is placed, the temperature measurement member is mounted on the circuit substrate, and a portion of the temperature measurement member is connected to the substrate.
