Lighting apparatus and projector

A projector, comprising:

• a lighting apparatus;
• an intensity modulation panel that generates image light by intensity-modulating illumination light from the lighting apparatus based on an intensity modulation signal;
• and
• a projection optical system that projects the image light, the lighting apparatus including:
• a light source;
• a phase modulation liquid crystal panel that includes a plurality of pixels, wherein the phase modulation liquid crystal panel modulates a phase of light from the light source for each of the plurality of pixels;
• a modulation signal corrector that performs signal correction that corrects a pixel modulation signal for a target pixel among the plurality of pixels based on a a pixel modulation signal for at least one peripheral pixel that is located around the target pixel to reduce a deviation amount relative to a desired amount of modulation of the target pixel;
• and
• an application voltage generator that generates an application voltage to be applied to each of the plurality of pixels based on the pixel modulation signal having been corrected by the modulation signal corrector.
