    摘要： Provided is a method for preparing an organic electronic device, comprising steps of: applying an ink composition on a substrate, on which an organic electronic element is formed; applying heat thereto before curing the applied ink composition; and curing the applied ink composition by irradiating with light having a wavelength in a range of 300 nm to 450 nm. Also provided is an organic electronic device, comprising a substrate, an organic electronic element formed on the substrate, and an organic layer sealing the entire surface of the organic electronic element, wherein after the organic layer is maintained at 110° C. for 30 minutes, the out-gas amount measured using Purge & Trap-gas chromatography/mass spectrometry is less than 150 ppm.

    摘要： The present invention relates to a method of bonding substrates and a substrate for displays manufactured by the same. In an embodiment, the method comprises (a) printing a first photocurable adhesive ink on the lower substrate to form a pattern; (b) photocuring the pattern to form a spacer on the lower substrate; (c) printing a second photocurable adhesive ink on the lower substrate, which includes the spacer, to form an adhesive layer; (d) irradiating the adhesive layer with light; and (e) laminating the upper substrate to the lower substrate via the adhesive layer, wherein the upper and lower substrates are transparent or opaque, and wherein the upper and lower substrates comprise the same or different materials.
