- the following HT-A compound was formed to a thickness of 100A, and Compound 1 was doped with a doping concentration of 30% by weight to form a P-type charge generation layer. Only the following HT-A compound was vacuum-deposited on the P-type charge generation layer to a thickness of 800 A to form a second hole transporting layer. The following BH-B compound and the following BD-B compound were vacuum deposited on the second hole transporting layer at a weight ratio of 96: 4 to a thickness of 250 A to form a second light emitting layer.
- the following ET-A compound and the following Li q compound were thermally vacuum deposited at a weight ratio of 1: 1 to a thickness of 300A to form a second electron transporting layer.
- LiF Li.sub.3Si.sub.2Fluoride
- an organic light emitting device was manufactured.
- An organic light emitting device was prepared in the same manner as in Experimental Example 2-1 except that the compounds described in the following Table 2 were used instead of the compound 1 in Experimental Example 2-1 .
- the HAT-CN compound, A compound and B compound, which are the compounds shown in Table 2 are the same as the compounds described in Table 1 above.
- Table 2 shows the driving voltage and efficiency of the organic light emitting devices manufactured in Experimental Examples 2-1 to 2-6 and Comparative Examples 2-1 to 2-3. At this time, the driving voltage and the efficiency were measured by applying a current density of 10 mA / cm < 2 & gt ;.
