Document Type and Number:
WIPO Patent Application WO/2020/075453
Kind Code:
A1
Abstract:
The present invention provides a film for a light emitting element that is useful for manufacturing a light emitting element having excellent luminance life. The present invention relates to: a film for a light emitting element that includes a crosslinked body having crosslinked groups, wherein the crosslinked body having the crosslinked groups is a crosslinked body of a crosslinked material having crosslinked groups, and the crosslinked group content of the film for a light emitting element is 0.015 mmol/g to 0.05 mmol/g; a light emitting element including said film for a light emitting element; and a method for analyzing crosslinked groups in a film for a light emitting element, wherein said analysis method comprises (1) a step for swelling the film for a light emitting element in a solvent, and (2) a step for measuring crosslinked groups in the swollen film for a light emitting element using nuclear magnetic resonance spectroscopy.
