Organic light-emitting display device

A light-emitting display device comprising:

• a substrate;
• a plurality of pixels on the substrate, each pixel including a light-emitting element;
• a plurality of bank layers on the substrate, each bank layer disposed between a corresponding pair of pixels in the plurality of pixels;
• and
• an encapsulation unit on the plurality of pixels, the encapsulation unit including:
• a lower inorganic encapsulation layer disposed on the plurality of pixels to encapsulate the plurality of pixels, and disposed on the bank and the light-emitting element,
• a plurality of organic encapsulation layers on the lower inorganic encapsulation layer, the plurality of organic encapsulation layers spaced apart from one another, and
• a plurality of upper inorganic encapsulation layers disposed on the plurality of organic encapsulation layers, wherein each adjacent pair of upper inorganic encapsulation layers are spaced apart from one another to form a gap at a location of at least one of the plurality of bank layers, and
• wherein an upper surface of the lower inorganic encapsulation layer contacts a lower surface of the plurality of upper inorganic encapsulation layers to minimize or prevent a permeation of external moisture or oxygen into the plurality of organic encapsulation layers disposed between the lower inorganic encapsulation layer and the plurality of upper inorganic encapsulation layers.
