A method for depositing a functional material on a substrate is disclosed. A plate having a first surface and a second surface is provided. A layer of light scattering material is applied onto the first surface of the plate, and a layer of reflective material is applied onto the second surface of the plate. After a group of wells has been formed on the second surface of the plate, a layer of light-absorbing material is applied on the second surface of the plate. Next, the wells are filled with a functional material. The plate is then irradiated with a pulse of light to heat the light-absorbing material in order to generate gas at an interface between the light-absorbing material and the functional material to release the functional material from the wells onto a receiving substrate.

Provided is a display device with high productivity and with reduced color shift in light-emitting elements and reduced degradation in light-emitting element characteristics. An electron transport film (4c) formed on a blue light-emitting film (4b) in B pixels is thicker than an electron transport film (6d) formed on a green light-emitting film (6b) and a red light-emitting film (6c) in G and R pixels so that the remaining film percentage of the electron transport film (4c) after exposure to heat generated by irradiation with laser light is higher than the remaining film percentage of the electron transport film (6d) after exposure to heat generated by irradiation with laser light.

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.
