WIPO Patent Application WO/2024/096035
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an organic electroluminescent element or an organic EL display panel that has excellent optical properties that do not depend on various conditions such as organic film thickness, partition material, pixel size, decompression drying step, or ink composition. The present invention pertains to an organic electroluminescent element having a functional film in which at least a functional layer 1 and a functional layer 2 are laminated, the flatness F of the film in which the functional layer 1 and the functional layer 2 are laminated exhibiting a value greater than both the flatness F of the functional layer 1 and the flatness F of the functional layer 2.
