Abstract: An object is to improve use efficiency of an evaporation material, to reduce manufacturing cost of a light-emitting device, and to reduce manufacturing time needed for a light-emitting device including a layer containing an organic compound. The pressure of a film formation chamber is reduced, a plate is rapidly heated by heat conduction or heat radiation by using a heat source, a material layer on a plate is vaporized in a short time to be evaporated to a substrate on which the material layer is to be formed (formation substrate), and then the material layer is formed on the formation substrate. The area of the plate that is heated rapidly is set to have the same size as the formation substrate and film formation on the formation substrate is completed by one application of heat.

Abstract: A display device having high light-extraction efficiency is provided. A low-power display device is provided. In a red or green pixel included in the display device, a light-emitting element, an optically functional layer, and a wavelength-conversion layer are stacked in this order. The light-emitting element emits blue light, the optically functional layer transmits the blue light and reflects red and green light, and the wavelength-conversion layer converts the blue light into red or green light. The blue light emitted by the light-emitting element passes through the optically functional layer and enters the wavelength-conversion layer, and red or green light is emitted to the outside. The red or green light emitted from the wavelength-conversion layer to the optically functional layer side is reflected by the optically functional layer and emitted to the outside, which improves light-extraction efficiency.
