Abstract
An EL element having a color filter formed on an upper electrode thereof enables a decrease in the pixel loss or line defects. In the EL element, a lower transparent electrode, first insulating layer, luminescent layer and upper transparent electrode are laminated on a glass substrate. Further, a color filter is formed on the upper transparent electrode. As the color filter there is used a posi-resist having an average molecular weight in a range of from 100 to 50000 or a nega-resist having a polymerization reaction percentage in a range of from 5% to 70%.
