Method for manufacturing microlens and method for manufacturing organic electroluminescence element

A method for manufacturing an organic electroluminescence element, the method comprising:

• forming a first electrode on a substrate;
• forming a bank on the substrate so that the bank overlaps with a first part of the first electrode;
• forming a substrate film on a second part of the first electrode with which the bank does not overlap, the substrate film including a polyolefin having a thickness between 1 to 20 nm;
• spraying a plurality of droplets to attach the plurality of droplets on the substrate film, each of the plurality of droplets having transparency characteristics, a contact angle between each of the plurality of droplets and the substrate film being more than 50 °;
• hardening the plurality of the droplets attached on the substrate film to form a plurality of microlenses on the substrate film, each of the plurality of microlenses and the first electrode including a same conductive material;
• forming an organic electroluminescence film on the plurality of microlenses;
• and
• forming a second electrode on the organic electroluminescence film, electrons being transferred between the first and second electrodes and passing the substrate film.
