PROBLEM TO BE SOLVED: To achieve different sensitivity of a sub pixel while suppressing degradation in luminous energy received by a pixel.SOLUTION: Respective pixels P1-P4 are divided into four sub pixels S1-S4 and on the respective pixels P1-P4, microlenses ML1, ML2 are disposed. The microlenses ML1, ML2 increase incident luminous energy into the sub pixels S1, S4 more than the sub pixels S2, S3 in the respective pixels P1-P4.SELECTED DRAWING: Figure 2 【課題】画素で受光される光量の低下を抑制しつつ、サブ画素の感度を異ならせる。【解決手段】各画素Ｐ１〜Ｐ４は、４個のサブ画素Ｓ１〜Ｓ４に分割され、各画素Ｐ１〜Ｐ４上には、マイクロレンズＭＬ１、ＭＬ２が配置され、マイクロレンズＭＬ１、ＭＬ２は、各画素Ｐ１〜Ｐ４において、サブ画素Ｓ２、Ｓ３に比べてサブ画素Ｓ１、Ｓ４への入射光量を増大させる。【選択図】図２
