摘要： A projector includes an illuminating device having a light source device, a first lens array having plural first small lenses, a second lens array having plural second small lenses corresponding to the plural first small lenses, and a superposing lens; an electro-optic modulator, and a projection optical system. A conjugate point of an image forming area in the electro-optic modulator is located on the light source device side or the projection optical system side from the vertex of a lens curved surface in each first small lens of the first lens array. An eccentric amount of each second small lens in the second lens array is adjusted such that each principal ray of the partial light beam passing through each first small lens in the first lens array passes an approximately central portion of the image forming area on the image forming area of the electro-optic modulator.

摘要： A projector capable of obtaining a smooth motion picture display of high quality without significantly reducing the utilization efficiency of light includes a light source device, a first lens array, a second lens array, a superimposing lens, a liquid crystal display device, and a projective optical system. The superimposing lens includes an anamorphic optical system to shape illumination luminous fluxes from the second lens array into illumination luminous fluxes having a cross-sectional shape that illuminates all the image formation regions of the liquid crystal display device in one direction along an X-axis direction, and a part of the image formation regions in the other direction along a Y-axis direction. The projector further includes a scanning device to scan the illumination luminous fluxes shaped by the superimposing lens in synchronism with a field frequency of the liquid crystal display device along the other direction on the image formation region.
