Abstract

A display panel and a display device, relating to the technical field of display. The display panel comprises a driving backplane (BP) and a light-emitting device (LD); the driving backplane (BP) comprises a plurality of pixel circuits (PC) distributed in an array along a row direction and a column direction; the pixel circuits (PC) each comprise a plurality of transistors, and the transistors in any pixel circuit (PC) include a driving transistor (T5); the driving transistor (T5) and at least some of the other transistors in any pixel circuit (PC) are metal oxide transistors; the driving backplane (BP) comprises a substrate (SU), and a semiconductor layer (SE) and at least one source/drain layer which are distributed in a direction distant from the substrate; channel portions of at least some of the transistors are located in the semiconductor layer (SE); the source/drain layer overlaps with channel portions of at least some of the metal oxide transistors; the light-emitting device (LD) is disposed on one side of the driving backplane (BP), and comprises a first electrode (ANO), a light-emitting layer (EL), and a second electrode (CAT) which are distributed in a direction distant from the driving backplane (BP); and a first electrode of the driving transistor (T5) is connected to the first electrode (ANO) of the light-emitting device (LD).
