    摘要: The present invention provides an evaluation method for evaluating whether a light-emitting element material to be evaluated is suitable for a host material or a guest material. By carrying out a first step of measuring absorption intensity of a light-emitting element material and a second step of irradiating the light-emitting element material with light for a predetermined period of time, repeatedly; thereby a change in absorption intensity with time is evaluated so that whether the light-emitting material is suitable for a host material or a guest material can be distinguished. The light emitted to the light-emitting element material preferably has a wavelength component which is absorbed by a skeleton which contributes to excitation of the light-emitting element material.

    摘要: An object is to provide a light emitting element with low drive voltage which contains an organic compound and an inorganic compound. One feature of a light emitting element of the present invention is to include a layer containing a light emitting material between a pair of electrodes, in which the layer containing a light emitting material has a layer containing a carbazole derivative represented by General Formula (1) and an inorganic compound which exhibits an electron accepting property to the carbazole derivative represented by General Formula (1). With such a structure, the inorganic compound accepts electrons from the carbazole derivative, carriers are generated internally, and a drive voltage of the light emitting element can be reduced.
