To provide an organic semiconductor device capable of suppressing a decrease in external quantum efficiency and having significantly improved photoelectric conversion efficiency.SOLUTION: An organic semiconductor device includes a compound represented by the following formula (1) in an active layer. (In formula (1), R1 and R2 are independently selected from 2-butyloctyl groups or longer-chain primary or secondary branched alkyl groups, respectively, and R3 and R4 are selected from linear or branched alkyl groups having 8 or more carbon atoms, each of which may independently have a substituent, R represents a halogen atom, and n represents an integer of 1 to 4 independently.SELECTED DRAWING: None 【課題】外部量子効率の低下を抑制でき、光電変換効率が大幅に改善された有機半導体デバイスを提供する。【解決手段】下記式（１）で表される化合物を活性層に含有する有機半導体デバイス。（式（１）中、Ｒ１及びＲ２は、各々独立に２−ブチルオクチル基又はそれよりも長鎖の１級または２級の分岐アルキル基から選択され、Ｒ３及びＲ４は、各々独立に置換基を有してもよい炭素数８以上の直鎖又は分岐鎖のアルキル基から選択され、Ｒはハロゲン原子を表し、ｎは各々独立に１〜４の整数を表す。）【選択図】なし
