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 (11, 12, 13) emit laser light (RGB) and an MEMS mirror (30) scans the laser light (RGB) and generates a display image (M).

An LD driving means (101) emits laser light (RGB) to the LDs (11, 12, 13) when the temperature is low, and causes the LDs (11, 12, 13) to perform self-heating driving for raising the temperature of themselves.
