Abstract
Description
図4は、本変形例に係る光源の模式図である。図4に示すように、本変形例では、筐体12の表面12aに凹部12bが形成されている。波長変換素子20は、その凹部12b内に配置されている。波長変換素子20の表面20aは、筐体12の表面12aと面一である。よって、本変形例では、波長変換素子20の側面が筐体12により覆われている。このため、波長変換素子20の側面からの光の出射が抑制されている。よって、波長変換素子20の表面20aから出射する光の強度を高めることができる。従って、出射光L3の強度を高めることができる。
図5は、第2の実施形態に係る液晶用バックライトユニットの模式図である。本実施形態の液晶用バックライトユニット2は、液晶表示装置のバックライトユニットとして用いられるものである。
図6は、第3の実施形態に係る液晶用バックライトユニットの模式図である。図7は、第4の実施形態に係る液晶用バックライトユニットの模式図である。
まず、ホウケイ酸系ガラスからなるガラス粉末85質量%に対し、CaS:Ce3+の蛍光体粉末15質量%を添加し、混合した後、焼成し、厚み0.2mmの波長変換基板を作製した。
実施例と同じ方法で作製した波長変換素子を、反射抑制層を形成した側の表面に光が照射されるようにエポキシ樹脂を用いて筐体と接着した後、実施例と同様の評価を行った。その結果、照射開始から約20分後に波長変換素子に破損が生じた。
