Abstract
A projection display device includes a plurality of reflective liquid crystal panels, a plurality of polarizers, and a combining optical system. The combining optical system includes a first incident surface to which first color light emitted from a first reflective liquid crystal panel and reflected by a combining surface of the combining optical system is incident and a second incident surface to which second color light emitted from a second reflective liquid crystal panel and passing through the combining surface is incident. The polarizes include a first polarizer, which reflects the first color light to the first incident surface, and a second polarizer which reflects the second color light to the second incident surface. An alignment direction of the liquid crystal of the first reflective liquid crystal panel is orthogonal to an alignment direction of the liquid crystal of the second reflective liquid crystal panel.
