摘要： Light-emitting elements have a problem that their light-extraction efficiency is low due to scattered light or reflected light inside the light-emitting elements. The light-extraction efficiency of the light-emitting elements needs to be enhanced by a new method. According to the present invention, a light-emitting element includes a first layer generating holes, a second layer including a light-emitting layer for each emission color and a third layer generating electrons between an anode and a cathode, and the thickness of the first layer is different depending on each layer including the light-emitting layer for each emission color. A layer in which an organic compound and a metal oxide are mixed is used as the first layer, and thus, the driving voltage is not increased even when the thickness is increased, which is preferable.

摘要： An object is to provide a deposition method for smoothly obtaining desired pattern shapes of material layers and a method for manufacturing a light-emitting device while throughput is improved when a plurality of different material layers is stacked on a substrate. A material layer is selectively formed in advance in a position overlapped with a light absorption layer over a first substrate by pump feeding. Three kinds of light-emitting layers are deposited on one deposition substrate. This first substrate and a second substrate that is to be a deposition target substrate are arranged to face each other, and the light absorption layer is heated by being irradiated with light, whereby a film is deposited on the second substrate. Three kinds of light-emitting layers can be deposited with positional accuracy by performing only one position alignment before light irradiation.
