Description
但し、本発明の目的がこのような目的に限定されるものではなく、本発明の思想及び領域から逸脱しない範囲で、様々に拡張可能である。
し、図4は、図2のII領域の一例を示している。
そこで、光学モジュールを配置した箇所について、必要な程度に光を透過させつつ、画像も表示する半透過・半表示領域とすることが提案されている。
(US2019/0130822A; 「先行文献2」の対応米国出願)
ところが、特には、有機発光表示装置(OLED)では、有機発光素子の配置箇所に、多数の絶縁膜が積層しており、層同士の界面で、反射が生じうる。そこで、互に接触して重ねられる絶縁膜同士の屈折率差を小さくすることも提案されている。(US10,062,865B)
なお、ゲート絶縁膜125及び層間絶縁膜135は、透過領域(TA)中に残しても良い(本願図5)。
すなわち、平面図で見て、サブ画素同士の間、透過領域(TA)同士の間、及び、サブ画素と透過領域(TA)との間には、必ず、遮光パターン(第1の周辺領域(SA1))が介在されるようにする。
なお、この遮光パターン(第1の周辺領域(SA1)は、通常表示領域(「第1の領域(A1)」)中にて各サブ画素を取り囲む遮光パターン(第2の周辺領域(SA1))と全く同様とすることができる。
