Embodiment approach 1
[0144] One aspect of the present invention is that any one of a benzocarbazole skeleton, a dibenzocarbazole skeleton, and a tribenzocarbazole skeleton and a carbazole skeleton, a benzocarbazole skeleton, a dibenzocarbazole skeleton, and a tribenzo An organic compound in which any of the carbazole skeletons is bonded to naphthalene-1,4-diyl or naphthalene-1,5-diyl. These skeletons or groups may also each include a substituent.
[0145] The organic compound according to one aspect of the present invention having such a structure has good hole transport properties, and is very suitable as a material constituting the hole injection layer of a light-emitting element, a material constituting the hole transport layer, and a light-emitting layer. The material of the host material. In addition, the organic compound of one embodiment of the present invention that does not include a polyacene skeleton as a substituent can also be suitably used as a material constituting an electron bloc...
Embodiment approach 2
[0245] FIG. 1 shows a light emitting element according to one embodiment of the present invention. A light-emitting element according to one embodiment of the present invention includes a first electrode 101 , a second electrode 102 , and an EL layer 103 . The EL layer uses the above-mentioned hole transport material containing an organic compound.
[0246]The EL layer 103 includes a light emitting layer 113 and may further include a hole transport layer 112 . The light-emitting layer 113 includes a light-emitting material and a host material, and the light-emitting device according to one embodiment of the present invention emits light from the light-emitting material. The organic compound of one embodiment of the present invention may be included in any part of the EL layer 103 , but is preferably used as a material for the light emitting layer 113 or the hole transport layer 112 .
[0247] In addition, although FIG. 1 illustrates the hole injection layer 111, the electron...
Embodiment approach 3
[0304] In this embodiment, a light-emitting device using the light-emitting element described in Embodiment 2 will be described.
[0305] In this embodiment mode, a light-emitting device manufactured using the light-emitting element shown in Embodiment Mode 2 will be described with reference to FIG. 2 . Notice, Figure 2A is a top view showing a light emitting device, and Figure 2B is along Figure 2A 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 .
[0306] Note that the lead wiring 608 is a wiring for transmitting signals input to the sourc...
