The lighting unit includes the DMDs 80R, 80G, and 80B. The lighting unit also includes: the prisms 50 and 60 combining the light emitted from the DMDs 80R, 80G, and 80B; and the light modulating optical device 90G. The incident light including the green component light and the yellow component light enters the light modulating optical device 90G. The light modulating optical device 90G transmits the green component light and changes a transmittance of the yellow component light depending on a change of a molecular state. Light having emitted from the light modulating optical device 90G enters the DMD 80G, which corresponds to the incident light.
