Description
図1は、第1の実施の形態に係るLED搭載用基板及びLEDチップの垂直断面図である。
第1の実施の形態に係るLED搭載用基板10によれば、光反射膜13を導電パターン12のパターン間ギャップ12a及び凹部12b内に形成することにより、LEDチップ20から発せられる光を効果的に反射し、下地基板11及び導電パターン12による吸収を抑えることができる。このため、LED搭載用基板10を用いて、光取出効率に優れる発光装置を製造することができる。
第2の実施の形態においては、LED搭載用基板10の製造方法の一例として、マスクを用いない塗布工程により光反射膜13を形成する製造方法を示す。
第2の実施の形態によれば、スクリーン印刷用のマスク等を用いずに光反射樹脂16を形成することができ、マスクパターンの精度等に影響を受けないため、高い精度で光反射膜13を形成することができる。
