Abstract: 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.
