摘要： A film-formation method whereby a minute pattern thin film can be formed on a deposition substrate, without provision of a mask between a material and the deposition substrate. Moreover, a light-emitting element is formed by such a film-formation method, and a high-definition light-emitting device can be manufactured. Through a film-formation substrate in which a reflective layer, a light-absorbing layer and a material layer are formed, the light-absorbing layer is irradiated with light, so that a material contained in the material layer is deposited on a deposition substrate which is disposed to face the film-formation substrate. Since the reflective layer is selectively formed, a film to be deposited on the deposition substrate can be selectively formed with a minute pattern reflecting the pattern of the reflective layer. A wet process can be employed for formation of the material layer.

摘要： When a light-emitting element having an intermediate conductive layer between a plurality of light-emitting layers is formed, the intermediate conductive layer can have transparency; and thus, materials are largely limited and the manufacturing process of an element becomes complicated by a conventional method. A light-emitting element according to the present invention is formed by sequentially stacking a pixel electrode, a first light-emitting layer, an intermediate conductive layer (including an electron injecting layer and a hole-injecting layer, one of which is island-like), a second light-emitting layer and an opposite electrode. Therefore, the present invention can provide a light-emitting element typified by an organic EL element in which a range of choice of materials that can be used as the intermediate conductive layer is broadened extremely, and which can realize a high light-emitting efficiency, a low power consumption and a high reliability, and further a display device using the light-emitting element.

摘要： A light emitting device that achieves long life, and which is capable of performing high duty drive, by suppressing initial light emitting element deterioration is provided. Reverse bias application to an EL element (109) is performed one row at a time by forming a reverse bias electric power source line (112) and a reverse bias TFT (108). Reverse bias application can therefore be performed in synchronous with operations for write-in of an image signal, light emission, erasure, and the like. Reverse bias application therefore becomes possible while maintaining a duty equivalent to that of a conventional driving method.
