摘要： Demands such as higher definition, higher opening aperture, and higher reliability on a full-color flat panel display have been increased. Such demands are big objects in advancing higher definition (increase in the number of pixels) of a light-emitting device and miniaturization of each display pixel pitch with reduction in size of the light-emitting device. An organic compound-containing layer is selectively deposited using a laser beam which passes through openings of a mask. An irradiated substrate provided with a light absorption layer and a material layer containing an organic compound and a deposition substrate provided with first electrodes are placed so as to face each other. The light absorption layer is heated by a laser beam which has passed through the openings of the mask, and the organic compound at a position overlapping with the heated region is vaporized, and accordingly the organic compound is selectively deposited over the deposition substrate.
