An arylamine compound, having a structure as shown in the following Formula 1:

• wherein a ring A is a substituted or unsubstituted 5- to 16-membered aliphatic hydrocarbon ring;
• L1, L2 and L3 are each independently a single bond, substituted or unsubstituted arylene with 6 to 30 carbon atoms, and substituted or unsubstituted heteroarylene with 3 to 30 carbon atoms;
• Ar1 is selected from the following substituted or unsubstituted groups:
• alkyl with 1 to 20 carbon atoms, cycloalkyl with 3 to 20 carbon atoms, aryl with 6 to 30 carbon atoms and heteroaryl with 3 to 30 carbon atoms;
• R1, R2, R3 and R4 are the same or different from each other, and are each independently selected from deuterium, halogen group, cyano, cycloalkyl with 3 to 20 carbon atoms, heterocycloalkyl with 2 to 20 carbon atoms, alkyl with 1 to 20 carbon atoms, aryl with 6 to 30 carbon atoms and heteroaryl with 3 to 30 carbon atoms;
• and a1, a2, as and a4 are the numbers of R1, R2, R3 and R4 respectively;
• a1 and a4 are each independently selected from 0, 1, 2, 3 or 4, and when a1 is greater than one, any two R1s are the same or different, or any two adjacent R1s are connected with each other to form a saturated or unsaturated ring with 3 to 15 carbon atoms;
• and when a4 is greater than one, any two R4s are the same or different, or any two adjacent R4s are connected with each other to form a saturated or unsaturated ring with 3 to 15 carbon atoms;
• a2 and a3 are each independently selected from 0, 1, 2 or 3, and when a2 is greater than one, any two R2s are the same or different, or any two adjacent R2s are connected with each other to form a saturated or unsaturated ring with 3 to 15 carbon atoms;
• and when a3 is greater than one, any two R3s are the same or different, or any two adjacent R3s are connected with each other to form a saturated or unsaturated ring with 3 to 15 carbon atoms;
• the substituents in the ring A are selected from the group consisting of deuterium, halogen group, cyano, alkyl with 1 to 15 carbon atoms, aryl with 6 to 12 carbon atoms and heteroaryl with 3 to 18 carbon atoms;
• the substituents in Ar1, L1, L2 and L3 are the same or different, and are each independently selected from the group consisting of deuterium, halogen group, cyano, heteroaryl with 3 to 30 carbon atoms, aryl with 6 to 30 carbon atoms which can be optionally substituted by 0, 1, 2, 3, 4 or 5 substituents selected from deuterium, fluorine, chlorine, cyano, methyl and tert-butyl, alkyl with 1 to 15 carbon atoms, cycloalkyl with 3 to 20 carbon atoms, heterocycloalkyl with 2 to 20 carbon atoms, aralkyl with 7 to 15 carbon atoms, heteroaralkyl with 4 to 15 carbon atoms, alkoxy with 1 to 30 carbon atoms, alkylthio with 1 to 30 carbon atoms, alkylsilyl with 1 to 30 carbon atoms, trialkylsilyl with 3 to 12 carbon atoms, triarylsilyl with 18 to 24 carbon atoms, aryloxy with 6 to 30 carbon atoms, and arylthio with 6 to 30 carbon atoms.
