摘要： An illumination apparatus includes a fluorescence unit, laser light irradiation means, and a beam integration unit. The fluorescence unit has a plurality of phosphors, in which the colors of fluorescence generated due to excitation differ, arranged in different regions. The laser light irradiation means irradiates laser light onto the regions of each color of the fluorescence unit while changing the position at which the laser light strikes the fluorescence unit. The beam integration unit integrates fluorescence from each region of the fluorescence unit on a display panel.

The plurality of cells includes a pair of cells adjacent to each other, which have spherical centers on second plane β parallel to first plane a and parts of spherical surfaces whose spherical radius differ, from each other, those parts being surfaces. The pair of cells satisfies the relationship of RI2−LI2=RO2−LO2, where RI is a spherical radius of the surface of one of the cells, RO is a spherical radius of the surface of the other cell, LI is a distance between the spherical center of the surface of one of the cells and a boundary surface between the pair of cells, and LO is a distance between the spherical center of the surface of the other cell and the boundary surface between the pair of cells.

摘要： A three-panel projection display apparatus displays a color image by separating light emitted from a light source into lights of three primaries, i.e., red, green, and blue, with dichroic mirrors, by irradiating liquid crystal light valves with the respective separated lights, by combining the lights modulated by the respective liquid crystal light valves with a cross dichroic prism, and by projecting the combined light through a single projection lens onto a screen. The lengths of the light paths for the separated blue and green lights are equal to each other. The distance between a condenser lens and the liquid crystal light valve in the blue light path is shorter than the distance between a condenser lens and the liquid crystal light valve in the green light path.

The excitation light synthesizing unit includes polarization splitter film (15), first and second ¼ wavelength plates (13 and 14), and reflection member (19). Polarization splitter film (15) transmits excitation light that is P-polarized light while reflecting excitation light that is S-polarized light. First and second ¼ wavelength plates (13 and 14) are arranged on the path along which first excitation light (L1), which is directed toward polarization splitter film (15), travels. Reflection member (19) disposed between first and second ¼ wavelength plates (13 and 14). Reflection member (19) reflects second excitation light (L2) incident via polarization splitter film (15) toward polarization splitter film (15). Reflection member (19) includes hole (20) formed to pass first excitation light (L1).
