Description
図1は、本実施形態に係る表示装置10の前面図である。表示装置10は、液晶パネル20と、液晶パネルの背面に沿って設けられた光源装置100と、液晶パネル20および光源装置100を支持する枠30とを備える。図1において、視認性のために液晶パネル20は背面側の光源装置100を透過するように示されている。図1に示す表示装置10に含まれる各部の数および大きさは実際の構成を反映しておらず、実際の実装方法に応じて任意に設計されてよい。
実施例として第1の実施形態に係る光源装置100に対して加速試験を行った。また、光源装置100から高熱伝導覆い材130およびヒートシンク150が省略された比較例1、ならびに光源装置100から高熱伝導覆い材130が省略された比較例2に対して加速試験を行った。加速試験の条件としては、発光素子121として中心波長450nmのLEDを用いて光源装置100を作製し、85度の環境温度においてLEDを点灯した。LED点灯前の状態および70時間経過後の状態についてそれぞれ全光束を測定し、それらの状態の間の全光束維持率を算出した。光束維持率は、比較例1を100%とした相対値として表されており、その値が高いほど量子ドットの劣化が抑制されているため良い。また、実施例、比較例1および比較例2についてそれぞれ外観検査を行った。外観検査は、量子ドット112および分散媒113の色が、劣化により黒くなる程度を評価したものである。測定結果を表1に示す。
図4は、図1のA-A線から見た本実施形態に係る表示装置10の断面図である。本実施形態においては、量子ドット構造体110の構成が第1の実施形態と異なる。量子ドット構造体110の構成以外は、第1の実施形態と同様である。
