摘要： A method of manufacturing a display panel includes preparing a substrate including a first area, a second area surrounding the first area, and a third area disposed between the first area and the second area, forming a first organic insulating layer in the third area, forming a metal material layer in the third area on the first organic insulating layer, forming a mask layer on the metal material layer, the mask layer comprising a first portion and a second portion spaced apart from each other, removing the metal material layer and the first organic insulating layer exposed by the mask layer by using the mask layer as a mask, and forming a light-emitting diode in the second area.
