SINGLE LCD TYPE PROJECTOR

摘要

The device is for minimizing the size and for satisfying the characteristic of focus by inserting mirrors in the optical system. The device comprises: a retrofocus lens(RF) locating perpendicular to the optical axis between the illumination lamp(L) enclosed by an envelope; a reflector(RM') and the single LCD panel(LP'); a plate reflector(PM) inclined by an angle( ) to the optical axis; and focusing lenses(FL') locating perpendicular to the optical axis and separated from the inclined plate reflector.
