ORGANIC ELECTROLUMINESCENT SUBSTRATE, AND ORGANIC ELECTROLUMINESCENT ELEMENT

WIPO Patent Application WO/2012/111662

A1

The present invention addresses the problem of providing an organic electroluminescent substrate exhibiting superior weather resistance. The present invention relates to an organic electroluminescent substrate formed by providing the underside of a liquid crystal polyester layer with a layer containing a white pigment. The liquid crystal polyester layer is preferably a layer formed from a liquid crystal polyester having a repeating unit represented by formula (1), a repeating unit represented by formula (2), and a repeating unit represented by formula (3); wherein the ratio of the content of the repeating units containing a 2, 6-naphthylene group to the total amount of all of the repeating units is at least 40mol%. (1) - O - Ar1 - CO - (2) - CO - Ar2 - CO - (3) - O - Ar3 - O - (Ar1 represents a 2, 6-naphthylene group, a 1, 4-phenylene group, or a 4, 4'-biphenylene group. Ar2 and Ar3 independently represent a 2, 6-naphthylene group, a 1, 4-phenylene group, a 1, 3-phenylene group, or a 4, 4'-biphenylene group.)
