Abstract
An ink containing an electroluminescent light emitting material is discharged onto a buffer layer. The discharge amount of the ink is larger than a maximum volume where the ink is retained by the surface tension thereof on the top surface of the buffer layer.
Claims3
A method for manufacturing an organic electroluminescent element including a first electrode, a buffer layer provided on the first electrode, a light emitting layer provided on the buffer layer and containing an electroluminescent light emitting material, and a second electrode provided on the light emitting layer, the method comprising the steps of:
- calculating a maximum volume where an ink is retained by surface tension thereof on a top surface of the buffer layer based on a surface of the buffer layer and a contact angle of the ink with the buffer layer, the ink being retained by surface tension on the top surface of the buffer layer;
- discharging onto the buffer layer an ink containing the electroluminescent light emitting material, a volume of the ink being larger than the maximum volume obtained in the calculating step;
- and
- obtaining the light emitting layer by drying the ink discharged on the buffer layer.
