Display apparatus and method of manufacturing the same

A display apparatus comprising a substrate comprising a central area and a peripheral area adjacent to the central area, the central area comprising a display area, the display apparatus further comprising:

• a first insulating layer on the substrate;
• a plurality of insulation patterns on the first insulating layer at the peripheral area and extending along a same plane that is substantially parallel to the substrate, at least two of the insulation patterns being spaced apart from each other in a direction from the display area toward an edge of the substrate;
• a plurality of grooves located adjacent to one of the insulation patterns;
• a thin-film transistor (TFT) at the central area of the substrate, the TFT comprising an active layer, the active layer being directly on the first insulating layer;
• and
• a central insulating layer at the central area on the substrate, the central insulating layer being disposed on or over the first insulating layer, and the central insulating layer being disposed on at least a conductive layer of the TFT,
• wherein a first one of the grooves corresponds to the edge of the substrate and a second one of the grooves is between the central insulating layer and one of the insulating patterns.
