Abstract

Provided is a display device for a vehicle that can, in a configuration in which the cost of parts is curbed, quickly raise the temperature of a laser light source (LD) in a low temperature environment, and quickly perform stable image output. The LDs () emit laser light (RGB) and an MEMS mirror () scans the laser light (RGB) and generates a display image (M). A convex mirror () reflects display light (L) indicating the display image (M) in an external direction via a translucent light-transmitting unit (). An LD driving means () emits laser light (RGB) to the LDs () when the temperature is low, and causes the LDs () to perform self-heating driving for raising the temperature of themselves.
