Abstract
A top-emission organic EL display device includes a substrate, pixel electrodes, auxiliary electrode, insulating layer formed between the pixel electrodes and includes an opening to expose the auxiliary electrode, organic EL layer formed on the pixel electrodes and includes organic layers, at least one formed on the auxiliary electrode, a contact portion being an opening of the organic layer formed on the auxiliary electrode, and transparent electrode layer formed on the organic EL layer and the contact portion. When an insulating layer overlap distance between the contact portion and pixel electrode adjacent to the contact portion with respect to the pixel electrode is regarded as 'a' and an insulating layer overlap distance between the contact portion and pixel electrode adjacent to the contact portion with respect to the auxiliary electrode is regarded as 'b', at least one of “a” and “b” is equal to or greater than 2 μm.
