1. A display panel, comprising:
a flexible substrate;
a driving circuit layer disposed on the flexible substrate, wherein the driving circuit layer comprises a plurality of first transistors and a plurality of second transistors;
a plurality of first light-emitting units disposed on a side of the driving circuit layer away from the flexible substrate, wherein each of the first light-emitting units is connected to a first source electrode or a first drain electrode of a corresponding one of the first transistors, and the first light-emitting units emit light from a side away from the flexible substrate; and
a plurality of second light-emitting units disposed on a side of the flexible substrate away from the driving circuit layer, wherein each of the second light-emitting units is connected to a second source electrode or a second drain electrode of a corresponding one of the second transistors through a connection hole penetrating through the flexible substrate, and the second light-emitting units emit light from a side away from the flexible substrate, and
wherein each of the first light-emitting units is an LED chip or an OLED light-emitting unit, each of the second light-emitting units is the LED chip or the OLED light-emitting unit, and at least one of the first light-emitting units is disposed between every adjacent two of the second light-emitting units.
