Abstract
A light emitting diode device including a substrate, a plurality of light emitting elements, and an encapsulant. The substrate has a front surface and a back surface opposite to the front surface. The substrate includes a first portion and a second portion. The first portion has a plurality of light-penetrating holes. The second portion is separated from the first portion. The light emitting elements are disposed adjacent to the light-penetrating holes and on the front surface of the first portion. The encapsulant is disposed on the front surface of the substrate, and covers the light emitting elements.
