Abstract
A method for producing a resin film by using a resin material and accurately forming a fine pattern as a vapor deposition mask or an optical element, a method for producing an organic EL display device, a base film for forming a fine pattern and a resin film with a supporting member are provided. A liquid resin material is applied onto a supporting member to form a resin coating film (S), and a temperature of the resin coating film is increased to a temperature at which the resin material cures, to form a baked resin film (S). Thereafter, a base film formed by the baked resin film attached to the supporting member is processed by irradiating with lasers, to form a resin film () having a desired fine pattern and the supporting member (S). Thereafter, the baked resin film on which the fine pattern is formed is peeled from the supporting member, and the resin film having the fine pattern is obtained (S).
