Title:
METHOD FOR PRODUCING ORGANIC ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/005976
Kind Code:
A1
Abstract:
The present invention provides a method by which an organic electronic device having a desired performance is able to be produced. A method for producing an organic electronic device according to one embodiment of the present invention comprises a functional layer formation step wherein a functional layer is formed on a first electrode layer on a substrate and a step wherein a second electrode layer is formed on the functional layer; and the functional layer formation step comprises a coating film formation step wherein a coating film is formed on the first electrode layer and a drying step wherein the coating film is dried within an infrared heating furnace, while conveying the substrate. If the infrared heating furnace is divided into a plurality of small regions, each having a length of 50 cm, from the carry-in port of the infrared heating furnace along the conveyance direction of the substrate, and N small regions where the substrate temperature at the downstream end of the small region is higher than the substrate temperature at the upstream end of the small region by 5°C or more are referred to as the first to Nth temperature-increasing small regions, the ith temperature-increasing small region has Mi infrared irradiation parts on the electrode layer formation surface side and the temperature of the Mi infrared irradiation parts is equal to or less than Th that is defined by the relational expression below, where Tf is the highest substrate temperature within the ith temperature-increasing small region.
Th< (5 × 109 + (Tf)4)0.25
