The invention provides an organic compound, an organic photoelectric device, application thereof and a display or lighting device, the structure of the organic compound is shown as a formula I or a formula II, Ar1 and Ar2 are respectively and independently selected from hydrogen, substituted or unsubstituted C6-C30 aryl, or substituted or unsubstituted C3-C30 heteroaryl; each of L1 and L2 is independently selected from a single bond, a substituted or unsubstituted C6-C30 aryl group, or a substituted or unsubstituted C2-C30 heteroaryl group; x1 is selected from the group consisting of C (R6) (R7), N (R6), O, S, and Si (R6) (R7). When the organic compound is applied to a light-emitting auxiliary layer, the hole movement degree can be improved, the hole transmission performance is improved, and then the light-emitting efficiency of a device is improved. 本发明提供了一种有机化合物、有机光电器件、其应用及显示或照明装置，其结构如式Ⅰ或式II所示：其中，Ar1和Ar2各自独立地选自氢、取代或未取代的C6～C30芳基、或取代或未取代的C3～C30杂芳基；L1和L2各自独立地选自单键、取代或未取代的C6-C30芳基、或取代或未取代的C2-C30杂芳基；X1选自由C(R6)(R7
