An optical lens assembly includes: a first element group including: a first lens group with positive refractive power, including one or two lenses; a second element group including: a second lens group with positive refractive power, including two or three lenses; an optical element including, in order from a visual side to an image source side: an absorptive polarizer, a reflective polarizer and a first phase retarder; and a partial-reflective-partial-transmissive element; and a third element group including an image source plane. The first element group, the second element group and the third element group are arranged in order from the visual side to the image source side. When the optical lens assembly satisfies a specific condition, the weight of the device can be reduced, the zoom function can be provided, and the image quality can be ensured.

An optical lens assembly includes, an optical element group; and in order from a visual side to an image source side: a first lens with positive refractive power, a second lens with refractive power, a third lens with refractive power, and an image source-side surface of the third lens being convex in a paraxial region thereof, and a partial-reflective-partial-transmissive element. Wherein the optical element group is disposed between the first lens and the third lens, and includes, in order from the visual side to the image source side: an absorptive polarizer, a reflective polarizer and a phase retarder. The optical lens assembly may become lightweight and have good image quality when satisfying a specific condition.
