    • A hole transporting region made of a hole transporting material, an electron transporting region made of an electron transporting material, and a mixed region (light emitting region) in which both the hole transporting material and the electron transporting material are mixed and which is doped with a triplet light emitting material for red color are provided in an organic compound film, whereby interfaces between respective layers which exist in a conventional lamination structure are eliminated, and respective functions of hole transportation, electron transportation, and light emission are exhibited. In accordance with the above-mentioned method, the organic light emitting element for red color can be obtained in which power consumption is low and a life thereof is long. Thus, the display device and the electric device are manufactured by using the organic light emitting element.
    • 由空穴传输材料制成的空穴传输区域,由电子传输材料制成的电子传输区域和混合有空穴传输材料和电子传输材料的混合区域(发光区域),并掺杂有 在有机化合物膜中设置用于红色的三重态发光材料,由此消除了存在于常规层压结构中的各层之间的界面,并且表现出空穴传输,电子传输和发光的各种功能。 根据上述方法,可以获得功耗低且寿命长的红色有机发光元件。 因此,通过使用有机发光元件来制造显示装置和电气装置。
