  • 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

  • Publication number: 20190041718
    Abstract: A light control device disposed between an outdoor area and an indoor area includes: a light-transmissive first electrode; a light-transmissive second electrode; a refractive-index control layer located between the first electrode and the second electrode, and having a controllable refractive index; and a light-transmissive recessed and protruding layer located between the first electrode and the refractive-index control layer, and including repeating protrusions, wherein the light control device is disposed such that the first electrode is on an outdoor area side, the repeating protrusions each have an inclined surface inclined at a predetermined angle of inclination, relative to a thickness direction of the light control device, and the angles of inclination of one of the repeating protrusions and another of the repeating protrusions are different in a recurrent direction of the repeating protrusions.
