A projection display device and a light source control method thereof capable of improving visibility of specific information without increasing a manufacturing cost and a power consumption amount are provided. An HUD includes a plurality of light sources that emit light beams with different colors, a projection unit that projects light according to image information among the light beams emitted from the plurality of light sources onto a combiner, and a light source control unit that sequentially emits lights from the plurality of respective light sources according to a predetermined light emission amount pattern. The light source control unit performs control for causing at least one of the light sources other than a specific light source among the plurality of light sources to emit light with a smaller light emission amount than a light emission amount of the specific light.

Optical disc manufacturing apparatus of the present invention comprises a nozzle for ejecting TV curable cationic composition, ultraviolet radiation means for radiating ultraviolet rays while the UV curable cationic composition dropping from the nozzle reaches a disc substrate; and superimposing means for superimposing the two disc substrates one upon another by allowing planes onto which the UV curable cationic composition is dropped to be faced. To allow the UV curable cationic composition to spread between the two disc substrates superimposed by the superimposing means: a statically placing plane for placing the disc should be provided. A stacking means for stacking the plurality of discs and rigid disc placing means for placing a rigid disc having a flat plane on the disc in the course of stacking the plurality of discs should be provided.

Optical disk production device

Ultraviolet rays are irradiated in a space through which a cationic ultraviolet curable composition falling from a nozzle passes before reaching a disc substrate. The cationic ultraviolet curable composition which has been irradiated with ultraviolet rays, is distributed in a ring form on the surface of the disc substrate. Another disc substrate is then superposed in this distributed surface to spread the composition by pressing or by the weight of the other disc substrate itself.
