Abstract: An organic light emitting display device includes: a thin film transistor disposed in a display area of a substrate; an insulating layer disposed on the thin film transistor; an organic light emitting element disposed on the insulating layer and connected to the thin film transistor; and an encapsulation layer covering the organic light emitting element. The encapsulation layer includes: a first inorganic layer extending from the organic light emitting element to a non-display area; an organic layer disposed on the first inorganic layer; a second inorganic layer extending from the organic layer to the non-display area; and an organic pattern layer disposed between the first inorganic layer and the second inorganic layer and spaced apart from the organic layer in the non-display area. At least a part of the first inorganic layer and at least a part of the second inorganic layer may contact each other in the non-display area.

Abstract: A method of preparing a patterned cured product, the method including: providing a composition including a sol-gel reactive silicon-containing monomer, a polymerizable (meth)acryl monomer, a photoinitiator, and a fluorinating agent on a substrate to form a first layer on the substrate; contacting the first layer with a master mold to form a second layer including a pattern transferred by the master mold; and obtaining the patterned cured product from the second layer, wherein obtaining of the patterned cured product from the second layer includes a sol-gel reaction, a photocuring reaction, and a separating of the master mold.
