Abstract
A display panel is provided. The display panel includes: a substrate having a display region and a bending region; a buffer layer having a first buffer layer disposed in the display region and a second buffer layer disposed in the bending region; a thin-film transistor disposed on the first buffer layer; an insulated combination layer disposed in the second buffer layer, a via hole is provided in the insulated combination layer and the second buffer layer; and a planarization layer disposed on the thin-film transistor and the insulated combination layer, and the planarization layer fills the via hole. A manufacturing method for a display panel is also disclosed. The present invention adopts an organic flat layer to fill the via hole, which can simplify the process flow and reduce the production cost while ensuring the flexibility of the bending region.
