Preparation of Organic EL Element 1-1
[0235]After a substrate, in which ITO had been deposited at nm on a glass plate as an anode (NA-45 produced by NH Techno Glass Co. Ltd.) was subjected to patterning, the transparent support substrate was washed with isopropyl alcohol by use of ultrasonic waves, followed by being dried with a dry nitrogen gas, and was subjected to UV ozone washing for 5 minutes. This transparent support substrate was fixed on a substrate holder of a vacuum evaporation system available on the market, and on the other hand, each of five resistance heating boats made of tantalum was charged with A-NPD, CA-1, Ir-12, BCP and Alq3, respectively, which was attached in the vacuum evaporation system (in the first vacuum chamber).
[0236]Further, a resistance heating boat made of tantalum was charged with lithium fluoride and a resistance heating boat made of tungsten was charged with aluminum, respectively, and these boats were attached in the second chamber of the vacuum ev...

Preparation of Organic EL Element 2-1
[0250]After a substrate, in which ITO had been deposited at 150 nm on a glass plate as an anode (NA-45 produced by NH Techno Glass Co. Ltd.) was subjected to patterning, the transparent support substrate was washed with isopropyl alcohol by use of ultrasonic waves, followed by being dried with a dry nitrogen gas, and was subjected to UV ozone washing for 5 minutes.
[0251]This transparent support substrate was fixed on a substrate holder of a vacuum evaporation system available on the market, and on the other hand, each of five resistance heating boats made of tantalum was charged with A-NPD, CA-1, Ir-13, BCP and Alq3, respectively, which was attached in the vacuum evaporation system (in the first vacuum chamber).
[0252]Further, a resistance heating boat made of tantalum was charged with lithium fluoride and a resistance heating boat made of tungsten was charged with aluminum, respectively, and these boats were attached in the second chamber of the ...

Preparation of organic EL Element 3-1
[0266]After a substrate, in which ITO had been deposited at 150 nm on a glass plate as an anode (NA-45 produced by NH Techno Glass Co. Ltd.) was subjected to patterning, the transparent support substrate was washed with isopropyl alcohol by use of ultrasonic waves, followed by being dried with a dry nitrogen gas, and was subjected to UV ozone washing for 5 minutes.
[0267]This transparent support substrate was fixed on a substrate holder of a vacuum evaporation system available on the market, and on the other hand, each of five resistance heating boats made of tantalum was charged with m-MTDATXA, CA-2, Ir-12, BCP and Alq3, respectively, which was attached in the vacuum evaporation system (in the first vacuum chamber).
[0268]Further, a resistance heating boat made of tantalum was charged with lithium fluoride and a resistance heating boat made of tungsten was charged with aluminum, respectively, and these boats were attached in the second chamber of ...
