Description
図1(a)〜(c)は、第1の実施の形態に係る発光素子1の製造工程を概略的に表す斜視図である。
このとき、樹脂膜20を完全に切断するため、透明基板11を僅かに削る程度の位置まで刃を入れることが好ましい。
第2の実施の形態は、クリア層が蛍光体含有層の側面を覆うように形成される点において、第1の実施の形態と異なる。なお、第1の実施の形態と同様の点については、説明を省略又は簡略化する。
第3の実施の形態は、第1、2の実施の形態に係る発光素子を有する発光装置についての形態である。なお、第1、2の実施の形態と同様の点については、説明を省略又は簡略化する。
上記実施の形態に係る発光装置によれば、複数の発光素子に含まれる蛍光体含有層を一括して形成するため、発光素子間の発光色のばらつきが小さい。また、個片化された発光素子の各々に蛍光体含有層を貼り付ける場合のように接着剤を使用する必要がないため、製造コストを低減することができる。

10 ウエハ
11 透明基板
12 発光部
