Abstract
A light emitting device includes a package substrate, a patterned conductive layer, an LED chip, and an encapsulation layer. The patterned conductive layer is located on top of the package substrate, and has an isolation region that separates the patterned conductive layer into a first region and a second region. The LED chip is located on top of the patterned conductive layer. The encapsulation layer covers the LED chip and the patterned conductive layer. The encapsulation layer forms an optical structure that corresponds to the LED chip in position and that has a lateral curved surface covering a side wall of the LED chip. When light emitted from the LED chip radiates through the optical structure, the light emitting device has a viewing angle exceeding 120°.
