A method of manufacturing a micro lens comprising: forming a first mold including a first lens profile shape including providing a first mold substrate and forming a first lens mold accommodating hole on the first mold substrate; forming a second mold including a second lens profile shape; aligning the second mold on one surface of a lens substrate comprising a hole; disposing a material at the hole; aligning the first mold on another surface of the lens substrate; applying a pressure onto the disposed material to form a first profile on the disposed material, in accordance with the first lens profile shape of the first mold, so the disposed material becomes a molded lens element; and hardening the molded lens element to form the micro lens; characterised in that: the formation of a first mold further includes aligning a first lens mold including the first lens profile shape, into the first lens mold accommodating hole; wherein in the aligning of the first lens mold into the first lens mold accommodating hole, a space between an outer surface of the first lens mold and an inner surface of the first lens mold accommodating hole has a same shape as a spacer portion of the micro lens; and the method of manufacturing a micro lens further comprises applying a pressure onto the disposed material to form a second profile on the disposed material, in accordance with the second lens profile shape of the second mold so that the disposed material becomes a molded lens element. forming a first mold including a first lens profile shape including providing a first mold substrate and forming a first lens mold accommodating hole on the first mold substrate; forming a second mold including a second lens profile shape; aligning the second mold on one surface of a lens substrate comprising a hole; disposing a material at the hole; aligning the first mold on another surface of the lens substrate; applying a pressure onto the disposed material to form a first profile on the disposed material, in accordance with the first lens profile shape of the first mold, so the disposed material becomes a molded lens element; and hardening the molded lens element to form the micro lens; characterised in that: the formation of a first mold further includes aligning a first lens mold including the first lens profile shape, into the first lens mold accommodating hole; wherein in the aligning of the first lens mold into the first lens mold accommodating hole, a space between an outer surface of the first lens mold and an inner surface of the first lens mold accommodating hole has a same shape as a spacer portion of the micro lens; and the method of manufacturing a micro lens further comprises applying a pressure onto the disposed material to form a second profile on the disposed material, in accordance with the second lens profile shape of the second mold so that the disposed material becomes a molded lens element. the formation of a first mold further includes aligning a first lens mold including the first lens profile shape, into the first lens mold accommodating hole; wherein in the aligning of the first lens mold into the first lens mold accommodating hole, a space between an outer surface of the first lens mold and an inner surface of the first lens mold accommodating hole has a same shape as a spacer portion of the micro lens; and the method of manufacturing a micro lens further comprises applying a pressure onto the disposed material to form a second profile on the disposed material, in accordance with the second lens profile shape of the second mold so that the disposed material becomes a molded lens element.
