摘要:
There is a problem in a dual emission device emitting light out of both surfaces that an image on the surface and an image on the rear surface are different from each other (either image is mirror-reversed). A dual emission device is disclosed in which either light emitted from the light-emitting device is reflected by glass including a semi-transmissive film to display on glass an image same as another image obtained also from the light-emitting device, and simultaneously, external information can be viewed through the glass. A mirror can be arranged between the dual emission device and the glass including a semitransparent film.

By irradiating a first substrate which is an evaporation donor substrate including a function layer in which films having different refractive indexes (high-refractive index films and low refractive index films) are stacked with first light (wavelength=λ1), a material layer over the first substrate is patterned, and by irradiating the first substrate with second light (wavelength=λ2) which is different from λ1, the material layer which is patterned is evaporated onto a second substrate which is a deposition target substrate.

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.

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.

To provide a light-emitting device from which uniform light emission can be obtained by providing an auxiliary wiring; a light-emitting device in which a short circuit between electrodes or between an electrode and an auxiliary wiring, which is attributed to a step caused by the auxiliary wiring, hardly occurs; and a light-emitting device which has high reliability by preventing a short circuit. In an EL light-emitting device including an auxiliary wiring, by covering a step caused by the auxiliary wiring is covered with an insulator, a short circuit between electrodes or between an electrode and the auxiliary wiring, which is attributed to the step caused by the auxiliary wiring, is prevented. Thus, the above objects are achieved.

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:
In the present invention, a first substrate which is an evaporation donor substrate is prepared in which a material layer is formed over a patterned reflective layer. A surface of the material layer over the first substrate is irradiated with first light which satisfies one predetermined irradiation condition to pattern the material layer. A surface opposite to the surface of the first substrate is irradiated with second light which satisfies another predetermined irradiation condition to evaporate the patterned material layer onto a second substrate, which is a deposition target substrate. According to the present invention, deterioration of a material included in the material layer can be prevented and a film pattern can be formed on the second substrate with high accuracy.
