Problems solved by technology

[0007] Compared with light-emitting devices with existing structures, light-emitting devices with this structure can have higher light extraction efficiency and external quantum efficiency, but it is difficult to integrate such light-emitting devices without adversely affecting other important characteristics of light-emitting devices. A layer with a low refractive index is formed inside the EL layer

Embodiment approach 1

[0114] 1,1-bis[4-[N,N-bis(p-tolyl)amino] is known as one of materials having a low refractive index among organic compounds having carrier transport properties that can be used in organic EL devices Phenyl]cyclohexane (abbreviation: TAPC). When a material with a low refractive index is used for the EL layer, the external quantum efficiency of the light-emitting device can be improved, so it is expected that a light-emitting device having a good external quantum efficiency can be obtained by using TAPC. However, since TAPC has a low glass transition point, it has a problem with heat resistance. In addition, TAPC can flow holes, but substantially cannot flow electrons.

[0115] Note that, in order to obtain a material with a low refractive index, it is preferable to introduce an atom having a small atomic refraction or a substituent having a low molecular refraction into the molecule. A saturated hydrocarbon group, a cyclic saturated hydrocarbon group, etc. are mentioned as a ...

Embodiment approach 2

[0251] In this embodiment, refer to 1A to 1E A light-emitting device using the organic compound shown in Embodiment 1 will be described.

[0252] >

[0253] exist 1A to 1E In the light-emitting device shown, Figure 1A and Figure 1C The light-emitting device shown has a structure (single structure) in which an EL layer is sandwiched between a pair of electrodes, whereas, Figure 1B , Figure 1D and Figure 1E It is a structure (tandem structure) in which a charge generating layer is sandwiched between an EL layer sandwiched between a pair of electrodes, and two or more layers are stacked. Note that the structure of the EL layer is the same in both structures. Furthermore, in Figure 1D In the case where the illustrated light-emitting device has a microcavity structure, a reflective electrode is formed as the first electrode 101 , and a semi-transmissive / semi-reflective electrode is formed as the second electrode 102 . Thus, the above-mentioned electrodes can be forme...
