  • Patent number: 10615243
    Abstract: The light-emitting device includes a flexible substrate, a lower barrier layer positioned above the flexible substrate, a light-emitting element and a thin-film transistor controlling the light-emitting element positioned above the lower barrier layer, a first upper barrier layer positioned above the light-emitting element and including a first inorganic material, and a second upper barrier layer positioned above the thin-film transistor and including a second inorganic material. The first upper barrier layer and the second upper barrier layer are spaced from each other at least in a region between the light-emitting element and the thin-film transistor.
    Type: Grant
    Filed: April 30, 2018
    Date of Patent: April 7, 2020
