Abstract
An illuminator according to the present disclosure includes a light source section and an optical phase modulator. The light source section emits light including first and second polarization components. The optical phase modulator generates and emits first illumination light (SDR illumination light) and second illumination light (HDR illumination light) The first illumination light is used in a light intensity modulator to generate an image in a first luminance region. The second illumination light is used in the light intensity modulator to generate an image in a second luminance region The optical phase modulator emits, as the first illumination light, light of the first polarization component without performing phase modulation. The optical phase modulator performs phase modulation on light of the second polarization component on the basis of the image in the second luminance region, and emits the phase-modulated light as the second illumination light.
