ABSTRACT:
To provide a projection type video display capable of reliably preventing a double image from being produced. A first light flux producer for producing a first light flux and a second light flux producer for producing a second light flux are arranged on the light emission side of a lamp. The light flux producer comprises a condenser lens, a rod integrator, and a pair of lenses. Lights passing through the pair of lenses are respectively refracted by condenser lenses, and are respectively introduced into first and second areas of a liquid crystal display panel in such a manner as to cross an optical surface in a color separating and mixing sector.
