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

A multi-screen display apparatus, comprising:

• a plurality of display devices disposed along at least one direction of a first direction and a second direction transverse to the first direction,
• wherein each of the plurality of display devices 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,
• wherein the device isolation line includes a protrusion tip protruding from the circuit layer to the dam, and
• wherein the self-emitting device is isolated by the protrusion tip of the device isolation line at the device isolation portion.
