Embodiment approach 1
[0168] 1,1-bis-(4-bis(4-methyl-phenyl)-ammonia is known as one of materials with a low refractive index among organic compounds having carrier transport properties that can be used in organic EL devices. -phenyl)-cyclohexane (abbreviation: TAPC). By using a material with a low refractive index for the EL layer, a light-emitting device with high external quantum efficiency can be obtained, so it is expected that a light-emitting device with good external quantum efficiency can be obtained by using TAPC.
[0169] In general, there is a trade-off relationship between high carrier transport and low refractive index. This is because carrier transport properties in organic compounds are mostly derived from the presence of unsaturated bonds and organic compounds having many unsaturated bonds tend to have a high refractive index. TAPC is a substance that has an excellent balance between hole transport properties and low refractive index. However, in compounds such as TAPC with 1,1-di...
