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