A display device includes: a display panel including signal lines in a display area and a peripheral area, the signal lines extending in a column direction and spaced apart; and test lines electrically connected to the signal lines in the peripheral area, extending in the column direction and arranged to be spaced apart. The peripheral area includes: a first peripheral area; and a second peripheral area located between the display area and the first peripheral area. The test lines include: a first test line including: a 1-1 testing portion disposed on the first peripheral area; and a 1-2 testing portion disposed on the second peripheral area; and a second test line including: a 2-1 testing portion disposed on the second peripheral area. A width of the 1-1 testing portion of the first test line is larger than a width of the 1-2 testing portion of the first test line.

Display device and method of testing display device

A display device including: a display panel including a plurality of pixels arranged therein; a plurality of gate lines disposed in the display panel to transfer gate signals to the pixels; and a gate driver disposed in the display panel to include a plurality of stages that generate gate signals and output them to the gate lines. A first one of the stages is connected with a first one and a second one of the gate lines through a gate pad, the gate pad includes a first gate pad, a second gate pad, and a third gate pad, and the first gate pad, the second gate pad, and the third gate pad are connected with each other through a gate pad connecting member.

Display device and method for manufacturing the same

A display device includes a first substrate including a display area and a peripheral area disposed in a periphery of the display area. A gate line is disposed in the display area. A data line is insulated from the gate line and intersects the gate line. The data line includes a first portion and a second portion. The first portion is disposed in the display area, and the second portion is connected to the first portion and is disposed in the peripheral area. A thin-film transistor (TFT) is disposed in the display area of the first substrate and is connected to the gate and data lines. A first insulating pattern is disposed on the TFT. A second insulating pattern is disposed in the peripheral area and covers a part of the second portion of the data line. The second insulating pattern includes a same material as the first insulating pattern.
