Abstract
A projector apparatus includes: a polarization beam splitter block assuming a shape of a rectangular parallelepiped that includes two end surfaces and four side surfaces; a light source opposed to one of the side surfaces; an illumination optical system disposed between the light source and the polarization beam splitter block, which converts illuminating light to substantially parallel light so that is directed to the polarization beam splitter block; a reflection-type liquid crystal display element opposed to an illuminating light output surface, through which an illuminating light undergone polarization separation is output, and that includes a rectangular display area through which the illuminating light is modulated to modulated light output to the polarization beam splitter block; and a projection optical system that forms a projection image with the modulated light undergone polarization separation, wherein: shorter borders of the rectangular display area is set parallel to the end surfaces.
