図1は、本技術を適用した表示素子の一実施の形態の構成の例を示すブロック図である。
ところで、有機EL表示素子において、画素を構成する各サブ画素の輝度を向上させるためには、サブ画素のサイズを変えることで、対応することが可能となる。しかしながら、画素のうちの特定のサブ画素のサイズを大きくして、発光面積を増大させる方法をとった場合には、画素ピッチが変わってしまうため、高精細化が困難となる。
図5は、第1の実施の形態の画素の構造の一部を示す要部断面図である。以下、この要部断面図を参照しながら、第1の実施の形態の画素10の構造を説明する。
図6は、第2の実施の形態の画素の構造の一部を示す要部断面図である。以下、この要部断面図を参照しながら、第2の実施の形態の画素10の構造を説明する。
図7は、第3の実施の形態の画素の構造の一部を示す要部断面図である。以下、この要部断面図を参照しながら、第3の実施の形態の画素10の構造を説明する。
次に、図8乃至図12を参照して、リフレクタ112の構造の詳細について説明する。
tan-1 (H / (L + t)) = θ + β - 90
tan(θ + β - 90) = H / (L + t) ・・・(5)
= 1000 × tan(51.3°+ 71°- 90°) / (1 - (tan(51.3°+ 71°- 90°) / tan71°))
= 808.07
次に、図13乃至図17を参照して、本技術の実施の形態の画素の製造工程の第1の例の流れを説明する。
次に、図18乃至図22を参照して、本技術の実施の形態の画素の製造工程の第2の例の流れを説明する。
