Abstract
A light-emitting device comprises a semiconductor layer; a pad electrode comprising a periphery disposed on the semiconductor layer; a finger electrode connected to the pad electrode, wherein the finger electrode comprises a first portion extended from the periphery of the pad electrode and a second portion connected to the first portion; and a plurality of first current blocking regions formed on the semiconductor layer, separated from the pad electrode and formed under the finger electrode, wherein one of the plurality of first current blocking regions is most close to the pad electrode and is separated from the pad electrode by a first distance, adjacent two of others of the plurality of first current blocking regions are separated from each other by a second distance, and the first distance is longer than the second distance.
