Title:
COMPOSITION FOR EL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/109927
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a novel composition for an EL device. In one aspect, the present invention addresses the problem of providing a composition for an EL device, whereby it becomes possible to manufacture an EL device having stable properties in a simple manner. In one aspect, the present invention addresses the problem of providing a composition for an EL device, whereby it becomes possible to manufacture an EL device having stable properties at low cost. Studies have been made on a composition for an EL device, which comprises different substances that are mixed together previously, and has such a property that the properties of the EL device is never altered even when the deposition with the composition is carried out repeatedly. As a result, a composition for an EL device is provided, which has such a property that the difference in 5% weight loss temperature between substances to be contained is 50°C or less under a pressure of 0.1 Pa or less.
