Abstract
A color electroluminescence(EL) display element and the manufacturing method thereof which can improve an RC-time delay phenomenon and the contrast of the EL display element. According to the EL display element, an auxiliary metal electrode is formed on a transparent electrode. The auxiliary metal electrode is formed by forming on the transparent electrode a metal film having a high melting point and a low resistivity, such as molybdenenum, with a thickness of about 1000 .ANG., and then by selectively etching the metal film so that it remains on the boundary between each of R, G, and B color filters with a width of about 5 to 30 .mu.m. The color filters are formed on a circular polarizing plate and sealed up with the auxiliary metal electrode, and thus the circular polarizing plate absorbs an external light incident to and reflected from a metal electrode.
