Abstract
A flexible display device is manufactured with high yield. A display device having high resistance to repeated bending is provided. The display device is manufactured by forming a separation layer over a support substrate; forming, over the separation layer, an inorganic insulating layer including a first portion and a second portion; forming a display element over the inorganic insulating layer to be overlapped with the first portion; forming a connection electrode over the inorganic insulating layer to be overlapped with the second portion; sealing the display element; separating the support substrate and the inorganic insulating layer using the separation layer; attaching a substrate to the inorganic insulating layer to be overlapped with the first portion; and etching the second portion using the substrate as a mask to expose the connection electrode.
