摘要:
A light-emitting device includes a substrate, a semiconductor stacked structure positioned on the substrate, a transparent electrode positioned on a first region of the semiconductor stacked structure, and at least one photonic crystal positioned in a second region of the semiconductor stacked structure. Preferably, the first region surrounds the second region, the area of the first region is larger than that of the second region, and the width of the second region is smaller than 40 micrometers. The structure of photonic crystals can be holes, pillars, continuous protrusions or depressions, discontinuous protrusions or depressions or the combination thereof, and the lattice of photonic crystals can be square, hexagonal, rectangular, periodic, multi-periodic, quasi-periodic or non-periodic.
