Abstract
A method for manufacturing a display device with low power consumption is provided. A method for manufacturing a display device includes a step of forming a first layer over a substrate by using a material containing a resin or a resin precursor, a step of forming a first region and a second region thinner than the first region in the first layer, a step of forming a first resin layer including a first region and a second region thinner than the first region by performing first heat treatment on the first layer in a gas containing oxygen, a step of forming, over the first resin layer, a layer to be separated including a display element, and a step of separating the layer to be separated and the substrate from each other. A step of forming a conductive layer over the first resin layer in a position overlapping with the second region is included in the step of forming the layer to be separated. A step of exposing the conductive layer by removing the first resin layer is included after the step of separating the layer to be separated and the substrate from each other.
