摘要：A projection type liquid crystal display device, including: irradiation meanshaving a function of irradiating light emitted from a light source upon an irradiatedsurface; a liquid crystal display element for modulating the light; and projection meansfor projecting the light emitted from said liquid crystal display element, wherein saidirradiation means comprises: at least one reflection mirror; a polarization beam splitterfor dividing the light from the light source into P polarization light and S polarizationlight; a lambda /2 phase shifting plate for rotating a direction of polarization of eitherone of the P polarization and S polarization lights; polarization means being constructedwith a reflection mirror for reflecting either one of the P polarization and S polarizationlights; a first lens array being constructed with a plurality of condenser lenses, forcollecting the light emitted from said polarization means so as to form a plurality ofsecondary light source images; and a second lens array being constructed with a pluralityof condenser lenses and positioned in vicinity of where the plurality of secondary lightsource images are formed.
