摘要： An illumination device of the present disclosure includes: a first light source unit that emits first light of a first wavelength band; a first spatial light modulator where the first light from the first light source unit enters; a second light source unit that emits second light of a second wavelength band; an integrator optical system including a first fly-eye lens where the second light from the second light source unit enters and generating illumination light for an illumination target on a basis of the first light having been modulated by the first spatial light modulator and the second light from the second light source unit; and a multiplexing optical system that multiplexes the second light having entered the first fly-eye lens and the first light having been modulated by the first spatial light modulator, in an optical path between the first fly-eye lens and the illumination target.

摘要： A transmissive-type display device having a display area which is sequentially scanned; and a lighting device arranged on a rear face of the display device, including lighting units arranged so as to be aligned in a direction from one toward the other end portion side along a direction in which the display area is sequentially scanned. The lighting units are in a light emitting state over a light emitting period after sequential scanning of display units including portions of the display area corresponding to the lighting units is completed, and the lighting units are sequentially scanned from one toward the other end portion side in accordance with the sequential scanning of the display area. A length of waiting time from the completion of sequential scanning of the display unit until the corresponding lighting unit emits light is nonlinearly decreased.

摘要： A projection display device includes a light source part including a first light source part that emits first color light and a second light source part that emits second color light having an emission intensity distribution different from that of the first color light, an image generator that generates an image on a basis of light emitted from the light source part, and a projection lens that projects the light outputted from the image generator onto a projection surface and has a projection optical axis that is shifted from a reference optical axis of the device as a whole. An emission optical axis of the first light source part is shifted to a direction opposite to a direction of the projection optical axis having been shifted.

摘要： A first projection display apparatus includes a color separator (41A) that has first and second incident surfaces (S1a and S1b), and allows light in first to third wavelength bands to pass therethrough or reflects the light in the first to third wavelength bands; first to third reflective light modulators (15); a first polarization splitter (12G); a second polarization splitter (12RB); and a projection optical system (19). Light in at least one of the first to third wavelength bands enters the first incident surface of the color separator as first polarized light, and light in the other wavelength bands enters the second incident surface of the color separator as second polarized light orthogonal to the first polarized light.
