Abstract: A lens assembly is provided. The lens assembly includes a first lens having a positive refractive power and a fixed position, a second lens having a positive refractive power and being movable in position with respect to an optical axis, and a third lens having a positive refractive power and being movable in position with respect to the optical axis together with the second lens, wherein a first film layer is disposed between the first lens and the second lens, wherein a mirror coating layer is disposed on one surface, which is configured to face a display, of at least one of the second lens or the third lens, wherein the first lens, the second lens, and the third lens are sequentially disposed along the optical axis from a user's eye side to a display side, and wherein a ratio of a distance from one surface of the first lens facing the user's eye side to an imaging surface of the display to a distance from one surface of the second lens facing the user's eye side to the imaging surface of the display satisfies a condition defined by 1.55>Tdiopter/TTL, where ‘total track length (TTL)’ represents the distance from the user's eye-side of the first lens to the imaging surface of the display, and ‘Tdiopter’ represents the distance from one surface of the second lens facing the user's eye-side to the imaging surface of the display.

Abstract: Provided are an optical assembly and an electronic apparatus having the optical assembly.
The optical assembly includes at least one reflective mirror reflecting image light output form a display module, a refractive lens through which image light reflected from the at least one reflective mirror passes, and a reflective lens having a first surface and a second surface and including a transflective coating layer provided on the first surface and reflecting the image light that passed through the refractive lens in a first direction and transmitting real light from a second direction facing the first direction.
