Abstract
A lens assembly is configured to be disposed under a cover glass, in a gap region and outside a display region, including a plurality of lenses, a reflector and an image sensor. The lenses, the reflector and the image sensor are sequentially arranged from an object side to an image side along an optical axis. One of the lenses is adjacent to the object side, has a minimum diameter of clear aperture, and has an outer circumferential portion which is non-circular. The lens assembly satisfies at least one of following conditions: BFL≥VL and BFL≥0.6×DL where BFL is a back focal length of the lens assembly, VL is a minimum side length of the image sensor, and DL is a diagonal length of the image sensor. A lens device includes a cover glass, a case, a display panel and the lens assembly.
