Abstract
The lighting unit includes the DMDs (R), (G), and (B). The lighting unit also includes: the prisms () and () combining the light emitted from the DMDs (R), (G), and (B); and the light modulating optical device (G). The incident light including the green component light and the yellow component light enters the light modulating optical device (G). The light modulating optical device (G) 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 (G) enters the DMD (G), which corresponds to the incident light.
