A method of manufacturing a light emitting device includes: forming a plurality of independent light emitting portions on a growth substrate; separating the light emitting portions from the growth substrate; mounting the light emitting portions onto a receiving substrate; and dicing the receiving substrate, onto which the light emitting portions are mounted, into a light emitting unit. Residual stress, which occurs when the light emitting portions are separated from the substrate, can be reduced, and the light emitting portions can be mounted onto the receiving substrate in a fluid state, whereby the light emitting device can be easily mass produced with excellent quality, and its manufacturing costs can be reduced.

A light emitting device package including a transparent cover having an electrode pattern formed on a bottom surface thereof; a light emitting device installed below the transparent cover and electrically connected to an external circuit via the electrode pattern; a fixing resin which fixes the light emitting device onto the bottom surface of the transparent cover; and a metal slug provided under the fixing resin to dissipate heat away from the light emitting device.

An optical lens is provided. The optical lens provides miniaturization and thin size, and reduces the cost and improves productivity by simplifying the structure and manufacturing process. The optical lens includes a light-transmitting substrate with a lens chamber and a fluidic chamber that are connected with each other. The optical lens also includes a light-transmitting elastic film which seals the lens chamber, a buffer elastic film which seals the fluidic chamber, and an actuator on the buffer elastic film which corresponds to the fluidic chamber, and varies the volume of the fluidic chamber to vary a pressure acting on the light-transmitting elastic film.
