摘要： A light emitting device having a structure in which oxygen and moisture are prevented from reaching light emitting elements, and a method of manufacturing the same, are provided. Further, the light emitting elements are sealed by using a small number of process steps, without enclosing a drying agent. The present invention has a top surface emission structure. A substrate on which the light emitting elements are formed is bonded to a transparent sealing substrate. The structure is one in which a transparent second sealing material covers the entire surface of a pixel region when bonding the two substrates, and a first sealing material (having a higher viscosity than the second sealing material), which contains a gap material (filler, fine particles, or the like) for protecting a gap between the two substrates, surrounds the pixel region. The two substrates are seated by the first sealing material and the second sealing material. Further, reaction between electrodes of the light emitting elements (cathodes or anodes) and the sealing materials can be prevented by covering the electrodes with a transparent protective layer, for example, CaF2, MgF2, or BaF2.

摘要： A sealing structure is provided without irradiating a pixel portion of a light emitting element by heat or UV light. By the sealing structure, the reliability is enhanced by blocking out oxygen and moisture, and preventing the deterioration of the light emitting element. The sealing structure in which a whole surface of the pixel portion is covered with a sealing material and which has an excellent sealing property is manufactured without being exposed to heat or UV light. In this case, a catalyst for curing a sealing material is formed as a film on a substrate, and a sealing material for covering a pixel portion is applied to the other substrate. Then, the both substrates are bonded together.

摘要： A measure for improving the light emission efficiency of a light emitting element without degrading characteristics of anode materials used in prior art is provided in manufacture of an upward emission type light emitting element. The present invention is characterized in that nitride or carbide of a metal element belonging to one of Group 4, 5, and 6 in the periodic table (hereinafter referred to as metal compound) is used as the material for forming an anode of a light emitting element. The metal compound has a work function equal to or larger than the work function of conventional anode materials. Therefore, injection of holes from the anode can be improved ever more. Also, with regard to conductivity, the metal compound is smaller in resistivity than ITO. It therefore can fulfil the function as a wire and can lower the drive voltage in the light emitting element compared to prior art.
