A purification method of a high-concentration sodium aluminate solution from a Bayer process comprises heating the high-concentration sodium aluminate solution to 80-120 DEG C, strongly mechanically stirring, adding a purifying agent into the sodium aluminate solution to desilicate and remove iron, organic substances and colored substances in the solution, and filtering to separate silica residue from insoluble substances to obtain the purified and decolorized sodium aluminate solution with absorbance lower than 0.30. The purifying agent is calcium oxide, magnesium oxide and/or calcined dolomite. The inventive method can perform deep desilication, remove iron and remove colored organic substances by one-step method.

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.
