Organic electroluminescence device and electronic appliance using the same
摘要
說明書
Compound BD-2 used as the dopant material is as follows.
From the results of Table 2, it can be seen that the organic EL devices of Examples 3 and 4 in which a specific host material and a specific dopant material are used in combination exhibit external quantum efficiencies of at least 1.2% and up to 1.6% higher than those of Comparative Examples 5 and 6.
The organic EL devices were fabricated and evaluated in the same manner as in Example 1 except that the compounds shown in Table 3 were used as the host material and the dopant material. The results are shown in Table 3.
