Embodiment approach 1

[0266] The organic compound of one aspect of the present invention is an organic compound represented by the following general formula (G1).

[0267] [chemical formula 14]

[0268]

[0269] In the above general formula (G1), B represents a substituted or unsubstituted naphthobisbenzofuran skeleton, a substituted or unsubstituted naphthobisbenzothiophene skeleton or a substituted or unsubstituted naphthobenzofuran benzothiophene skeleton. Skeleton B is bonded to one or two substituted or unsubstituted arylamino groups (i.e., q is 1 or 2), however, this arylamine is characterized as follows: not only amines having simple aryl groups such as phenyl groups, Rather, it is an arylamine including at least one of a substituted or unsubstituted dibenzofuryl group, a substituted or unsubstituted dibenzothienyl group, and a substituted or unsubstituted carbazolyl group.

[0270] In the above general formula (G1), A represents a substituted or unsubstituted dibenzofuryl group, a subs...

Embodiment approach 2

[0484] Refer to the following Figure 1A An example of a light-emitting element according to one embodiment of the present invention will be described in detail.

[0485] The light-emitting element of this embodiment includes a pair of electrodes including an anode 101 and a cathode 102 , and an EL layer 103 provided between the anode 101 and the cathode 102 .

[0486]The anode 101 is preferably formed using a metal, an alloy, a conductive compound, a mixture thereof, or the like with a large work function (specifically, 4.0 eV or more). Specifically, for example, indium oxide-tin oxide (ITO: Indium Tin Oxide, indium tin oxide), indium oxide-tin oxide containing silicon or silicon oxide, indium oxide-zinc oxide, tungsten oxide and zinc oxide Indium oxide (IWZO), etc. Although a film composed of these conductive metal oxides is usually formed by a sputtering method, it can also be formed by applying a sol-gel method or the like. An example of a formation method includes a me...

Embodiment approach 3

[0565] In this embodiment mode, a light-emitting device using the light-emitting element described in Embodiment 1 will be described.

[0566] A light emitting device according to one embodiment of the present invention will be described with reference to FIG. 4 . Figure 4A is the top view of the light emitting device, Figure 4B is along Figure 4A Cross-sectional views of A-B and C-D cut in. This light-emitting device includes a driver circuit unit (source line driver circuit) 601 , a pixel unit 602 , and a driver circuit unit (gate line driver circuit) 603 indicated by dotted lines as a unit for controlling light emission of the light-emitting element. In addition, reference numeral 604 is a sealing substrate, reference numeral 605 is a sealing material, and the inside surrounded by the sealing material 605 is a space 607 .

[0567] The lead wiring 608 is a wiring for transmitting signals input to the source line driver circuit 601 and the gate line driver circuit 603, ...
