Display device
View Patent ↗A structure including a first resin layer and a second resin layer sandwiching a self-light emitting element layer, a first stopper layer, a first resin sacrificial layer and a first glass substrate which are stacked on the first resin layer on the opposite side of the self-light emitting element layer, and a second glass substrate stacked on the second resin layer is prepared. The first glass substrate is peeled off from the first resin sacrificial layer by irradiating the first glass substrate with a laser beam. The first resin sacrificial layer is decomposed by a chemical reaction using a gas. The first stopper layer has a resistance to the chemical reaction, and the first resin sacrificial layer is removed while leaving the first stopper layer in a step of decomposing the first resin sacrificial layer.
