Electroluminescence display and manufacturing method of same, mask and manufacturing method of same

摘要

In an EL display having an EL element in which an emissive element layer is formed between an anode and a cathode, projections (pillars) (20) are formed on a base structure (10) in a region outside the emissive region, so that a hole transport layer, an emissive layer, and an electron transport layer can be formed through evaporation while the distance from the mask is maintained. Alternatively, the pillars (20) can be formed on the mask.
