Abstract
A light emitting device including first and second electrodes spaced apart from each other on a substrate, at least one bar-type LED having a first end on the first electrode and a second end on the second electrode, and an insulative support body between the substrate and the bar-type LED. The at least one bar-type LED has a length greater than a width.
Claims25
