    摘要： PROBLEM TO BE SOLVED: To provide a lighting device with high uniformity of brightness and better visibility and an electric apparatus using the same. SOLUTION: The lighting device uses organic compound materials as light-emitting media, and emits coherent light and incoherent light or luminescent light and laser light at the same time or individually from the organic compound materials. The device uses a material emitting electroluminescence, and in order to emit laser light in addition to the light emission from the material, a plurality of different organic compound materials are laminated with their wavelengths in consideration, a film thickness of each layer and a lamination structure are determined in accordance with purposes.

    摘要： The light-emitting element includes: a light-emitting layer (213) and a layer for controlling the movement of carriers (214) between a first electrode (202) and a second electrode (204). The layer for controlling the movement of carriers contains a first organic compound and a second organic compound, and is provided between the light-emitting layer and the second electrode. The first organic compound has an electron transporting property, and the second organic compound has an electron trapping property. The weight percent of the first organic compound is higher than that of the second organic compound. The light-emitting layer emits light when a voltage is applied such that the potential of the first electrode is higher than that of the second electrode. The first organic compound having the electron transporting property may be replaced with an organic compound having a hole transporting property, and the second organic compound having the electron trapping property may be replaced with an organic compound having a hole trapping property.
