    Abstract: A display device includes a pixel circuit, a first line disposed on the pixel circuit and a second line disposed on a same layer as the first line. A light emitting element is disposed on the first line and the second line. A connection pattern is disposed on a same layer as the first line and the second line and is disposed between the first line and the second line. The connection pattern connects the pixel circuit and the light emitting element. The connection pattern has a polygonal shape including at least six sides. A first vertex of the connection pattern is positioned at a shortest distance from the first line to the connection pattern and portions of the connection pattern between the first vertex and adjacent vertices are positioned farther from the first line than the first vertex.

    Abstract: A display device includes a display area and a non-display area disposed around the display area and including a pad area. The display device includes a resistance checker disposed in the non-display area, resistance test pads disposed in the pad area, resistance test lines connecting the resistance checker with the resistance test pad, and crack test lines disposed on the outer side of the resistance checker. The resistance test lines intersect the crack test lines in a plan view.
