An optical lens assembly includes, in order from a visual side to an image source side: a first lens with positive refractive power; an optical element including, in order from the visual side to the image source side, an absorptive polarizer, a reflective polarizer and a first phase retarder; a second lens with positive refractive power; a partial-reflective-partial-transmissive element; a second phase retarder; and an image source plane. The optical lens assembly has a total of two lenses with refractive power. A focal length of the optical lens assembly is f, a maximum image-source height of the optical lens assembly is INM, a focal length of the first lens is f1, a focal length of the second lens is f2, and following conditions are satisfied: 0.40<IMH/f<1.26 and 0.21<f2/f1<2.35. A head-mounted electronic device includes the optical lens assembly.
