摘要： Disclosed is an electroluminescent element (10) which includes an anode layer (12), a cathode layer (14), a first low refractive index layer (13) that is formed between the anode layer (12) and the cathode layer (14), a recessed portion (16) that penetrates at least the anode layer (12) and the first low refractive index layer (13), a second low refractive index layer (19) that is formed on the bottom of the recessed portion (16), and a light emitting portion (17) that is formed on the second low refractive index layer (19). The electroluminescent element (10) is also characterized in that the refractive index of the first low refractive index layer (13) and the refractive index of the second low refractive index layer (19) are lower than the refractive index of the light emitting portion (17). The electroluminescent element (10) provides an electroluminescent element which has high light-emitting efficiency when the light emitted from the light emitting portion is taken out from the substrate side.
摘要翻译：公开了一种电致发光元件（10），其包括形成在阳极层（12）和阴极层（14）之间的阳极层（12），阴极层（14），第一低折射率层（13），至少穿透所述阳极层（12）和所述第一低折射率层（13）的凹部（16），形成在所述凹部（16）的底部上的第二低折射率层（19）和形成在第二低折射率层（19）上的发光部分（17）。电致发光元件（10）的特征还在于，第一低折射率层（13）的折射率和第二低折射率层（19）的折射率低于发光部分（的折射率） 17）。电致发光元件（10）提供当从基板侧取出从发光部分发出的光时具有高发光效率的电致发光元件。
