摘要： Although an ink jet method known as a method of selectively forming a film of a high molecular species organic compound, can coat to divide an organic compound for emitting three kinds (R, G, B) of light in one step, film forming accuracy is poor, it is difficult to control the method and therefore, uniformity is not achieved and the constitution is liable to disperse. In contrast thereto, according to the invention, a film comprising a high molecular species material is formed over an entire face of a lower electrode connected to a thin film transistor by a coating method and thereafter, the film comprising the high molecular species material is etched by etching by plasma to thereby enable to selectively form a high molecular species material layer. Further, the organic compound layer is constituted by a material for carrying out luminescence of white color or luminescence of single color and combined with a color changing layer or a coloring layer to thereby realize full color formation.

摘要： A light-emitting device and a lighting device each including a light-emitting element which can recover from a short circuit between a pair of electrodes by itself without adversely affecting the characteristics of the element is provided. An oxide layer is provided so as to be in contact with an electrode of the light-emitting element, whereby, due to heat generated when a short circuit is caused between a pair of electrodes, oxygen in the oxide layer and an electrode material in a short-circuited part are reacted with each other and the electrode material in the short-circuited part can be an insulator. Further, by providing an oxide layer in contact with an electron-injection layer containing an alkaline earth metal, an oxide of the alkaline earth metal can be formed, whereby moisture that enters the insulator formed by an insulation phenomenon in the short-circuited part can be adsorbed and removed.
