Light emitting element, light emitting device, and electronic appliance |
摘要 |
<p>It is an object to provide a light emitting element capable of low-voltage driving; with high luminous efficiency; with high emission luminance; and with long emission lifetime. It is another object to provide a light emitting device and an electronic appliance in which power consumption is reduced; and which can be manufactured at low cost. A light emitting element is provided, including a light emitting layer (102) and a layer including a composite material (103) between a first electrode (101) and a second electrode (104), where the light emitting layer includes a base material and an impurity element, the layer including the composite material includes an organic compound and an inorganic compound, the layer including the composite material is provided to be in contact with the second electrode, and light emission is obtained by application of a voltage so that an electric potential of the second electrode is higher than that of the first electrode.</p> |
