Lighting device and projector device

A projector device, comprising:

• a light emitting unit that emits a plurality of light beams of different wavelength bands;
• a phase modulator that performs spatial light phase modulation on incident light beams from the light emitting unit and in which the light beams of the different wavelength bands are incident from the light emitting unit on respective phase modulation areas that are areas into which a phase modulation surface on which the spatial light phase modulation is performed is divided;
• an intensity modulator that performs spatial light intensity modulation on the light beams incident via the phase modulator;
• a projection lens that projects the light beams subjected to the spatial light intensity modulation by the intensity modulator on a projection surface;
• and
• a control unit that simultaneously executes the spatial light phase modulation in the phase modulation areas in a state in which the light beams of the corresponding wavelength bands are incident on the respective phase modulation areas.
