The display apparatus includes a substrate having a display portion, a plurality of pixels disposed in the display portion, a common electrode disposed in the display portion and electrically connected to each of the plurality of pixels, an auxiliary electrode electrically connected to an auxiliary voltage line extended from an edge portion of the substrate to the display portion, a height control layer provided between the substrate and the auxiliary electrode, and an auxiliary electrode contact portion disposed between the plurality of pixels, wherein the common electrode may be in contact with the auxiliary electrode covering a side of the height control layer in the auxiliary electrode contact portion.

Display apparatus and multi-screen display apparatus including the same

A light emitting display apparatus includes a substrate including a first region and a second region surrounded by the first region, a passivation layer disposed over the substrate, a planarization layer disposed over the passivation layer disposed in the second region of the substrate, a barrier structure disposed in the first region of the substrate, a light emitting device layer including a self-emitting device disposed over the planarization layer and the barrier structure, and an encapsulation layer including an organic encapsulation layer disposed over the light emitting device layer and at least a portion of the barrier structure, the barrier structure isolates the self-emitting device and blocks the spread of the organic encapsulation layer, at the first region of the substrate.

Light emitting display apparatus and multi-screen display apparatus including the same

A light emitting display apparatus includes a substrate configured to include a display area, a planarization layer disposed over the display area, a groove line disposed along a periphery portion of the substrate and configured to surround a lateral surface of the planarization layer, a dam configured to surround the groove line, a light emitting device layer configured to include a self-emitting device disposed over the planarization layer, the groove line, and the dam, and an encapsulation layer configured to include an organic encapsulation layer disposed over an encapsulation region surrounded by the dam, the organic encapsulation layer is configured to be filled in the groove line and is configured to surround a lateral surface of the light emitting device layer and the lateral surface of the planarization layer, and the self-emitting device is configured to be isolated at each of the groove line and the dam.

Light emitting display apparatus and multi-screen light emitting display apparatus including the same

A light emitting display apparatus includes a substrate including a display area, a circuit layer disposed in the display area, a planarization layer disposed over the circuit layer, a dam disposed over the circuit layer along a periphery portion of the substrate, a device isolation portion disposed in the circuit layer and including a device isolation line surrounding the dam, and a light emitting device layer including a self-emitting device disposed over the planarization layer, the dam, and the device isolation portion, the device isolation line may comprise a protrusion tip protruding from the circuit layer to the dam, and the self-emitting device may be isolated by the protrusion tip of the device isolation line at the device isolation portion.

Disclosed are embodiments of a narrow bezel display. The narrow bezel display has a structure in which output terminals of gate circuits are connected to jumping units through wires having a multistage path, thereby reducing the bezel size of a display. A dielectric layer may be disposed under the multistage path without placing another wire layer thereunder to prevent non-uniform capacitance between the wires and an underlying wire layer. Thus, a dimming phenomenon may be prevented during operation of the display or a short circuit may be prevented during an electrostatic test.
