A display device includes a substrate including a display area and a non-display area; a first overcoating layer disposed on the substrate and including a base portion and a protruding portion protruding from the base portion; a first hydrogen blocking layer disposed on a top surface of the protruding portion in the display area; a first electrode covering the base portion and the first hydrogen blocking layer; a bank disposed on a part of the first electrode; an organic layer disposed on the first electrode and the bank; and a second electrode disposed on the organic layer.

Display device with hydrogen blocking layer to minimize diffusion of hydrogen to transistor

An electroluminescent display device includes a substrate including a display area and a non-display area including a gate-in-panel (GIP) area disposed outside the display area, an oxide thin-film transistor disposed above the substrate, a planarization layer disposed above the oxide thin-film transistor, an anode disposed above the planarization layer, a bank disposed above the planarization layer and including an opening portion through which a part of the anode is exposed, a plurality of dams disposed outside the GIP area and configured by the planarization layer and the bank, a buffer layer disposed above the bank and the dam and made of silicon nitride, a light-emitting part disposed on the exposed anode and the buffer layer, and a cathode disposed on the light-emitting part, thereby inhibiting hydrogen from entering an oxide thin-film transistor and improve properties and reliability of the transistor.

Electroluminescent display device

A light emitting display apparatus and a multi-screen display apparatus including the same are disclosed. The light emitting display apparatus include a substrate, a light emitting device layer including a light emitting device disposed on the substrate, a dam pattern portion disposed at an edge portion of the substrate, an encapsulation layer disposed on the light emitting device layer and including an organic material disposed in an inner region surrounded by the dam pattern portion, and a device isolation portion disposed at the edge portion of the substrate to isolate the light emitting device, the dam pattern portion includes a discontinuous dam pattern disposed along the edge portion of the substrate.
