To provide a light detection device having excellent detection performance.SOLUTION: A light detection device of one embodiment disclosed herein includes: a first pixel including a first filter that transmits light of a first wavelength and a first photoelectric conversion section that photoelectrically converts the light of the first wavelength transmitted through the first filter; a second pixel including a second filter that transmits light of a second wavelength and a second photoelectric conversion section that photoelectrically converts the light of the second wavelength transmitted through the second filter; and a plurality of third pixels each including a light-dispersing section including a structure having a dimension equal to or less than a wavelength of incident light and a third photoelectric conversion section that photoelectrically converts light of a third wavelength transmitted through the light-dispersing section. The first pixel and the second pixel are each adjacent to six of the third pixels.SELECTED DRAWING: Figure 3 【課題】良好な検出性能を有する光検出装置を提供する。【解決手段】本開示の一実施形態の光検出装置は、第１波長の光を透過する第１フィルタと、前記第１フィルタを透過した第１波長の光を光電変換する第１光電変換部とを有する第１画素と、第２波長の光を透過する第２フィルタと、前記第２フィルタを透過した第２波長の光を光電変換する第２光電変換部とを有する第２画素と、入射光の波長以下の大きさの構造体を含む分光部と、前記分光部を透過した第３波長の光を光電変換する第３光電変換部とを有する複数の第３画素とを備える。前記第１画素及び前記第２画素は、それぞれ、６つの前記第３画素と隣り合う。【選択図】図３
