Backplane and method for manufacturing the same, backlight module, and display apparatus

Abstract

A backplane includes a substrate, a circuit structure layer, a reflective layer, a plurality of electronic devices and a plurality of encapsulation portions. Each encapsulation portion covers an electronic device in the plurality of electronic devices. At least one first conductive line includes a first linear extending portion, a second linear extending portion and a third linear extending portion that are sequentially connected. Orthographic projections of the first linear extending portion, the second linear extending portion, the third linear extending portion and an encapsulation portion in the plurality of encapsulation portions on the substrate are respectively a first orthographic projection, a second orthographic projection, a third orthographic projection and a fourth orthographic projection. The first orthographic projection is located within the fourth orthographic projection, the second orthographic projection is partially overlapped with the fourth orthographic projection, and the third orthographic projection is located outside the fourth orthographic projection.
