    • A method for forming a film in which throughput is improved and a desired pattern is obtained smoothly in stacking a plurality of material layers over a substrate and a method for manufacturing a light emitting device are provided. In advance, a material layer is formed selectively by a droplet discharge method to be in contact with a light absorption layer on a first substrate. A second substrate is disposed so that the material layer faces the second substrate. The light absorption layer is irradiated with a laser light so that a film containing a material included in the material layer is formed on the second substrate. When the light absorption layer have a desired pattern, a film reflecting the pattern of the light absorption layer that has undergone the laser light irradiation is formed on the second substrate.
    • 提供了一种形成胶片的方法,其中提高了生产量并且平滑地获得了在基板上层叠多个材料层的期望图案以及制造发光器件的方法。 预先通过液滴喷射方法选择性地形成材料层以与第一基板上的光吸收层接触。 第二基板被设置成使得材料层面向第二基板。 用激光照射光吸收层,使得包含在材料层中的材料的膜形成在第二基板上。 当光吸收层具有期望的图案时,在第二基板上形成反映经过激光照射的光吸收层的图案的膜。

    • 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。
