摘要： A binder material layer including an evaporation material is formed over a main surface of an evaporation source substrate, a substrate on which a film is formed is placed so that the binder material layer and a main surface thereof face each other, and heat treatment is performed on a rear surface of the evaporation source substrate so that the evaporation material in the binder material layer is heated to be subjected to sublimation or the like, whereby a layer of the evaporation material is formed on the substrate on which a film is formed. When a low molecular material is used for the evaporation material and a high molecular material is used for the binder material, the viscosity can be easily adjusted, and thus, film formation is possible with higher throughput than conventional film formation.

摘要： An object is to provide a white light-emitting element which emits broad white light which is close to natural light and covers a wide wavelength range; that is, a white light-emitting element which has a broad spectrum waveform. Further, there are various different kinds of white light; however, in particular, an object is to provide a white light-emitting element which emits white light which is close to the standard white color of the NTSC. Over a substrate 100, a second light-emitting element 110 and a first light-emitting element 120 are stacked in series. The first light-emitting element 120 exhibits a light emission spectrum having two peaks (two peaks in the blue to green wavelength range) and is disposed close to a film of light-reflecting material. The second light-emitting element 110 exhibits a light emission spectrum having a peak in the orange to red wavelength range, and is disposed in a position which is not close to the film of light-reflecting material.
