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

The light-emitting element 150 may be formed over an electrode electrically connected to a field-effect transistor (FET), for example, which is formed over any of the above-described substrates. Accordingly, an active matrix display device in which the FET controls the driving of the light-emitting element 150 can be manufactured.

The structure described above in this embodiment can be combined with any of the structures described in the other embodiments as appropriate.

Embodiment 4

In this embodiment, a light-emitting element having a structure different from that described in Embodiment 3 and light emission mechanisms of the light-emitting elements will be described below with reference to FIGS. 3A to 3C. In FIGS. 3A and 3B, a portion having a function similar to that in FIGS. 1A to 1C is represented by the same hatch pattern as in FIGS. 1A to 1C and not especially denoted by a reference numeral in some cases. In addition, common reference numerals are used for portions having similar functions, and a detailed description of the portions is omitted in some cases.

<Structure Example 3 of Light-Emitting Element>

FIG. 3A is a schematic cross-sectional view of a light-emitting element 250.
