Abstract: Disclosed herein is an organic light-emitting display device having a first flexible substrate; a second flexible substrate; a plurality of organic light-emitting pixels on the first flexible substrate and between the first flexible substrate and the second flexible substrate; an encapsulation unit covering the pixels; and an adhesive layer on the encapsulation unit. The Young's modulus of the adhesive layer is equal to or larger than a value so that the first flexible substrate is not deformed by bending stress when it is rolled up.

Abstract: The present disclosure relates to a lateral-type vacuum deposition apparatus, and a source block and a source assembly for the same. Disclosed are a source block that may simplify a lateral-type vacuum deposition apparatus and a lateral-type vacuum deposition apparatus using the same. The source block has a predetermined shape. In the lateral-type vacuum deposition apparatus, the substrate and the source block may face away each other. Accordingly, the lateral-type vacuum deposition apparatus including the source block is free of a conduit for transferring a vaporized source to a nozzle, thereby simplifying a structure of the apparatus. In particular, the source block may have a visible light transmittance of at least about 10% and may exhibit excellent shape maintenance ability during a lateral-type vacuum deposition process.
