Description
[2]前記nパッド電極を前記第3の隙間と挟む前記n電極上の位置、及び前記pパッド電極を前記第3の隙間と挟む前記p電極上の位置に設けられ、前記アンダーフィルに接触する、硬化前の前記アンダーフィルの流れを阻害するための流動阻害部を備えた、上記[1]に記載の発光装置。
[3]前記第2の隙間の前記第3の隙間への合流点が、前記第3の隙間の長さ方向の中間点からずれた位置にある、上記[1]又は[2]に記載の発光装置。
[4]前記第3の隙間の長さ方向の一方の端部を含む一部の領域において、前記第3の隙間の幅が前記端部に向かって広がっている、上記[1]~[3]のいずれか1項に記載の発光装置。
[5]前記n電極及びp電極の厚さが1.0μm以上である、上記[1]~[4]のいずれか1項に記載の発光装置。
図1は、第1の実施の形態に係る発光装置1の上面図である。図2は、図1の切断線A-Aにおいて切断された発光装置1の垂直断面図である。なお、図1においては、アンダーフィル16及び封止樹脂17の図示を省略している。
本発明の第2の実施の形態に係る発光装置は、発光素子20の外側を流れる硬化前のアンダーフィル16の流れを抑制する流動阻害部を電極12上に有する。なお、第1の実施の形態と同様の部材については、同じ符号を付し、その説明を省略又は簡略化する。
上記第1の実施の形態に係る発光装置1によれば、隙間G1及び隙間G2が設けられていることにより、配線基板10と発光素子20の間の空間におけるアンダーフィル16へのボイドの混入を抑えることができる。
