Abstract
A projection lens unit is provided that is reduced in size and profile. The projection lens unit may include a plurality of lenses of which at least one lens disposed at the base end opposite to the projection direction is cut away at the upper portion thereof. The surface of the cut-away portion of the lens is made flat. With this arrangement, a space above the lens can be used when a cooling fan is disposed above an electrooptical unit provided in the vicinity of the projection lens unit, whereby a projector can be reduced in size and profile, because the height of the projector can be reduced because it is not necessary to provide an additional space for receiving the cooling fan in the projector.
