Abstract
A top-emitting display unit is fabricated by the following steps: A lower electrode is formed on a substrate. An organic layer including a luminescent sublayer is formed on the lower electrode. Furthermore, an upper electrode containing lithium is formed by a sputtering process into a thickness of 7 nm to 21 nm. The upper electrode functions as a cathode. The lithium content in the upper electrode is in the range of 0.3 to 1.9 percent by weight. In the sputtering process, the upper electrode is preferably formed at a deposition rate of 50 nm/min or less.
