Abstract
A micro-lens array and manufacturing method. A hybrid micro-lens in which a refractive lens and a diffraction lens are formed includes: a refractive lens; a first ultraviolet hardening material which is bonded on a curved surface of the refractive lens to form an aspheric surface; a support substrate including a concave portion into which the refractive lens is inserted and supported; and a diffraction lens which is formed at a position corresponding to the refractive lens disposed on the support substrate.
