摘要:
An object is to provide a light-emitting module in which a light-emitting element suffering a short-circuit failure does not cause wasteful electric power consumption. Another object is to provide a light-emitting panel in which a light-emitting element suffering a short-circuit failure does not allow the reliability of an adjacent light-emitting element to lower. Focusing on heat generated by a light-emitting element suffering a short-circuit failure, provided is a structure in which electric power is supplied to a light-emitting element through a positive temperature coefficient thermistor (PTC thermistor) thermally coupled with the light-emitting element.

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 sealed 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 chelate complex having as its central metal tungsten which is an inexpensive metal and which is a heavy atom is applied to an organic light emitting element, thereby obtaining an organic light emitting element capable of converting the triplet excitation energy into light emission. By applying the organic light emitting element using this metal complex, an inexpensive light emitting device which is bright but consumes little power can be provided as well as an electric appliance using the light emitting device.
