Display device

摘要

A display device including a display area and a non-display area surrounding the display area. The non-display area includes a test data line (TDL) which receives a test data signal from an external source, a plurality of connection line units (CLUs) which connect the data lines and the TDL, and a dummy line unit which is formed in the non-display area. Each of the CLUs includes a test switch having an input terminal connected to the TDL, an output terminal connected to one of a plurality of data lines disposed in the display area, and a control terminal connected to a test switch control line which receives a test switch control signal from an external source. At least one of the CLUs includes a disconnection portion which interrupts the TDL, wherein both ends of the disconnection portion are connected to the dummy line unit by bypass connection lines, respectively.
