DISPLAY DEVICE

To provide a display device configured to improve moisture permeation characteristics without using a plastic substrate.SOLUTION: A display device includes: a first substrate including an active area having a plurality of sub pixels and a non-active area enclosing the active area, the first substrate comprising one of a transparent conductive oxide or an oxide semiconductor; an inorganic layer provided on the first substrate; a planarization layer provided on the inorganic layer; a second substrate provided on the planarization layer, the second substrate having an end located inside the first substrate; a seal member covering a portion of a top of the second substrate; an adhesive layer provided on the second substrate, the adhesive layer being spaced apart from the seal member; and a back cover bonded to the second substrate through the adhesive layer. Bubbles generated due to a step difference between the second substrate and the seal member are blocked, thereby reducing a crack which may be generated in an inorganic layer.SELECTED DRAWING: Figure 1 【課題】プラスチック基板を使用せず透湿特性が改善された表示装置を提供すること。【解決手段】本発明の一実施例に係る表示装置は、複数のサブ画素を含む表示領域及び表示領域を囲む非表示領域を含み、透明伝導性酸化物と酸化物半導体のうち一つからなる第１基板、第１基板上に配置される無機層、無機層上に配置される平坦化層、平坦化層上に配置され、末端が第１基板の内側に位置する第２基板、第２基板の上部の一部を覆うように配置されるシール部材、シール部材と離隔されて第２基板上に配置される接着層、及び接着層上に配置され、接着層により第２基板と接着されるバックカバーを含む。従って、シール部材と第２基板間の段差による気泡発生を遮断して無機層のクラック（ｃｒａｃｋ）発生が低減され得る。【選択図】図１
