description A projection display device includes: a light source device which emits source light; a first polarizer passes the source light in a first polarization state; a reflective liquid crystal panel; an illumination optical system which causes the source light to be incident to the reflective liquid crystal panel; a second polarizer passes the source light in the first polarization state from the first polarizer, and reflects the source light in a second polarization state from the reflective liquid crystal panel; a projection optical system which projects the source light reflected by the second polarizer; a support member which includes an outer member that supports the first polarizer and the reflective liquid crystal panel and an inner member that is fixed to the outer member in an internal space of the outer member and supports the second polarizer; and a seal mechanism which seals the internal space.
