ABSTRACT:
An illuminator comprising two light source sections (101, 102), a rod integrator (1), and a relay lens system (4) for introducing a light flux emitted from the rod integrator (1), wherein the rod integrator (1) is a columnar optical element having an incident end face (130F) and an exit end face (130B). One pair of opposite side faces out of four side faces are formed so that the planes face each other in parallel while the other pair of opposite side faces form a taper face where the planes face each other while inclining at a specified angle such that the opposite side faces recede from the incident end face (130F) toward the exit end face (130B). Lights from the two light source sections (101, 102) are converged to the vicinity of the incident end face (130F) of the rod integrator (1).
