Photoelectric conversion element and imaging device

An imaging device comprising

• a plurality of pixels that is each provided with photoelectric conversion elements as one or more organic photoelectric conversion sections, wherein
• the photoelectric conversion elements each include a first electrode,
• a second electrode that is disposed to be opposed to the first electrode, and
• a photoelectric conversion layer that is provided between the first electrode and the second electrode, the photoelectric conversion layer including a hole transporting material as a first organic semiconductor material, the hole transporting material absorbing blue light,
• wherein the hole transporting material includes a dithieno [2,3-d:
• 2′,3′-d′] benzo [1,2-b:
• 4,5-b′ldithiophene derivative represented by a general formula (1) or a general formula (2) as follows:
• where R1, R2, R3, and R4 each independently represent a phenyl group, a biphenyl group, a terphenyl group, a naphthalene group, a phenylnaphthalene group, a biphenylnaphthalene group, a binaphthalene group, a thiophene group, a bithiophene group, a terthiophene group, a benzothiophene group, a phenyl benzothiophene group, a biphenyl benzothiophene group a benzofuran group, a phenyl benzofuran group, a biphenyl benzothiophene group, an alkane group, a cycloalkane group, a fluorene group, a phenylfluorene group, a carbazole group, or a derivative thereof.
