Abstract

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.
