Embodiment approach 1
[0102] In this embodiment mode, a benzotriphenylene compound which is an organic compound of one embodiment of the present invention will be described.
[0103]
[0104] One aspect of the present invention is a benzotriphenylene compound represented by the general formula (G1-1).
[0105]
[0106] In the general formula (G1-1), A represents a condensed ring. In addition, R 1 to R 9 and R 11 to R 14 Each independently represents any of hydrogen, an alkyl group having 1 to 6 carbons, a cycloalkyl group having 3 to 6 carbons, and a substituted or unsubstituted aryl group having 6 to 13 carbons. In addition, Ar represents an arylene group having 6 to 13 carbon atoms, the arylene group may have a substituent, and the substituents may be bonded to each other to form a ring.
[0107] In addition, in the general formula (G1-1), the condensed ring is preferably selected from substituted or unsubstituted carbazolyl, substituted or unsubstituted naphthocarbazolyl, substituted o...
Embodiment approach 2
[0163] In this embodiment, refer to Figure 1A to Figure 1C The structure of a light-emitting device including the benzotriphenylene compound described in Embodiment Mode 1 will be described.
[0164]
[0165] First, the following will refer to Figure 1A to Figure 1C The structure of a light emitting element according to one embodiment of the present invention will be described.
[0166] Figure 1A It is a schematic cross-sectional view of a light emitting element 150 according to one embodiment of the present invention.
[0167] The light emitting element 150 includes the EL layer 100 provided between a pair of electrodes (the first electrode 101 and the second electrode 102 ). The EL layer 100 includes at least a light emitting layer 130 . Note that although in this embodiment mode, the first electrode 101 of the pair of electrodes is used as an anode and the second electrode 102 is a cathode, the structure of the light emitting element 150 may also be such that the fir...
Embodiment approach 3
[0248] In this embodiment, refer to Figure 2 to Figure 3B A light-emitting element having a different structure from the light-emitting element described in Embodiment Mode 2 will be described.
[0249]
[0250] figure 2 It is a cross-sectional view showing a light emitting element of one embodiment of the present invention.
[0251] exist figure 2 used in Figure 1A to Figure 1C The same hatching is shown with Figure 1A to Figure 1C Parts with the same functions are sometimes omitted from reference numerals. Additionally, with Figure 1A to Figure 1C Parts shown having the same functions are denoted by the same reference numerals, and detailed explanations thereof are sometimes omitted.
[0252] The light emitting element 250 includes a first electrode 101 and a second electrode 102 on the substrate 200 . In addition, a light emitting layer 123B, a light emitting layer 123G, and a light emitting layer 123R are included between the first electrode 101 and the second ...
