An optical lens module configured to receive at least one image light beam from an image source side is provided. The optical lens module includes a plurality of lens elements. The plurality of lens elements includes a first lens element to a fifth lens element arranged in sequence along an optical axis from an object side to the image source side, and the optical lens module have a semi-reflective layer, a phase retardation layer and a polarization reflection layer respectively formed on the surfaces of a part of the plurality of lens elements. The optical lens module has an aperture on the object side. Wherein, the optical lens module is a secondary imaging optical system, and the at least one image light beam is transmitted through the optical lens module to form an intermediate image between the aperture and the image source side.

A zoom projection lens with eleven lens elements is provided. The zoom projection lens sequentially includes a first lens group, a second lens group, a third lens group, an aperture stop, a fourth lens group and a fifth lens group along an optical axis from a screen side to an image source side. The first lens group has a negative refractive power and includes three lens elements. The second lens group has a positive refractive power and includes one lens element. The third lens group has a positive refractive power and includes one lens element. The fourth lens group has a negative refractive power and includes four lens elements. The fifth lens group has a positive refractive power and includes two lens elements. A first lens element in the first lens group is an aspheric lens made of plastic.
