摘要

A novel organic compound is provided. Moreover, a light-emitting element with high emission efficiency and a long lifetime is provided. A novel organic compound having a bicarbazole skeleton and a benzofuropyrimidine skeleton or a benzothienopyrimidine skeleton that includes at least one condensed ring or two condensed rings is provided. Moreover, a light-emitting element including the organic compound is provided.

說明書

In this example, fabrication examples of light-emitting elements, which are different from the light-emitting elements described in Example 3, each including the organic compound of one embodiment of the present invention and characteristics of the light-emitting elements are described. A comparative light-emitting element 3 was also fabricated. A cross-sectional view of the structure of each of the elements fabricated in this example is similar to that in FIG. 1A. Table 3 shows details of the element structure. In addition, structures and abbreviations of compounds used here are given below. Note that the above example can be referred to for other organic compounds.
