Abstract: Disclosed herein are a display device, and a method of testing a display device. The display device includes sub-pixels arranged along pixel columns, wire pads disposed in a non-display area and disposed on one side of the display area, fan-out lines extending in a first direction and connecting the sub-pixels with the wire pads, data lines extending in the first direction and connected to the fan-out lines, connection wires connecting the fan-out lines with the data lines, at least one of the connection wires including a first portion passing through the display area and extending in a second direction crossing the first direction; and a test unit disposed between the wire pads and the display area and electrically connected to the fan-out lines. The test unit applies a test voltage to the fan-out lines to check a short-circuit or an open-circuit in the fan-out lines.
