Abstract
An organic light-emitting diode (OLED) display panel, a fabrication method thereof, and an electronic apparatus including the OLED display panel are provided. The OLED display panel comprises: a substrate, an organic light-emitting device, and a capping layer. A material of the capping layer includes a compound of a chemical formula (I), L1, L2, L3, and L4 are independently selected from a hydrogen atom, a substituted or -unsubstituted alkyl, a substituted or unsubstituted alkenyl, a substituted or unsubstituted alkynyl, and a substituted or unsubstituted phenyl. A total quantity of benzene rings included in L1, L2, L3, and L4 is from 0 to 6. Y1, Y2, Y3, Y4, Y5, and Y6 are independently selected from a hydrogen atom, a substituted or unsubstituted alkyl, a substituted of unsubstituted alkenyl, and a substituted or unsubstituted alkynyl.
