Disclosed are a lens unit and a method of manufacturing the same. The lens unit includes a lens part including a curved region having a predetermined curvature; and a support part including a hole, in which the lens part is installed, and attached to the lens part at a lateral side of the hole. The lens part having the curvature and the support part of the lens unit are formed in separate processes such that the hole is formed in the support part having the strength, and the lens part is formed by filling the hole with the lens part, so that the movement of resin caused by shrinkage of the lens part when the lens part is cured is inhibited, and the support part and the lens part does not form the layered structure, thereby allowing the lens unit to be formed with a thin thickness.

Lens unit, manufacturing method of the same, and camera module including the same

Provided are a lens unit, a lens assembly, a camera module, a method of fabricating the camera module and the lens assembly, a method of fabricating an optic member, and an apparatus of fabricating the optic member. The lens unit comprises a lens portion and a supporting portion. The lens portion has a curved surface. The supporting portion extends from the lens portion. The supporting portion comprises a protrusion or a recess. The method of fabricating the optic member comprises injecting a resin composition inside a mold die, pressing the resin composition; and irradiating light onto the resin composition. Due to the pressure, shrinkage of a photo-curable resin composition can be reduced, and thus, the lens unit comprising the protrusion or recess can be easily fabricated.

A color-separating apparatus for a liquid crystal projector of single panel type that is capable of improving light efficiency and color revival property. In the apparatus, a color filter has red, green and blue colors formed in a spiral shape. A reflective plate is opposed to the color filter to reflect an incident light reflected and emitted from the color filter into the color filter again. Accordingly, a color light is transmitted with no light loss.
