First Claim
Patent Images
1. A display device, comprising:
- a substrate including a peripheral area around a display area;
a plurality of pixels in the display area of the substrate; and
a plurality of signal lines on the substrate and connected to the pixels, wherein the signal lines include;
a plurality of data lines connected to the pixels,a crack detection line connected to at least one of first data lines, but fewer than all of the data lines, through source/drain terminals of one or more first transistors, the crack detection line in the peripheral area,a test voltage line connected to second data lines through source/drain terminals of second transistors, the first and second data lines being connected to different pixels, anda control line connected to gates of the one or more first transistors.

Abstract
A display device includes a peripheral area around a display area, a plurality of pixels in the display area, and a plurality of signal lines connected to the pixels. The signal lines include a plurality of data lines connected to the pixels, a crack detection line connected to first data lines among the data lines through a first transistor, and a control line connected to a gate of the first transistor. The crack detection line is in the peripheral area.

13. A display device, comprising:
-
a display area including a plurality of pixels; a non-display area; a crack detection line extending in the non-display area, wherein the crack detection line is connected to at least one internal data line between first and last data lines through a source/drain terminal of a first transistor, and fewer than all data lines; and a test voltage line connected to other data lines between the first and last data lines through source/drain terminals of second transistors, wherein the at least one internal data line and the other data lines are connected to different pixels. - View Dependent Claims (14, 15, 16, 18, 20)

19. A display device, comprising:
-
a substrate including a peripheral area around a display area; a plurality of pixels in the display area of the substrate; and a plurality of signal lines on the substrate and connected to the pixels, wherein the signal lines include; a plurality of data lines connected to the pixels, a first crack detection line connected to first data lines among the data lines through a source/drain terminal of a first transistor, the first crack detection line on substantially left side of the peripheral area, a second crack detection line connected to second data lines among the data lines through a source/drain terminal of a second transistor, the second crack detection line on substantially right side of the peripheral area, wherein the first data lines are different from the second data lines, a test voltage line connected to third data lines through source/drain terminals of third transistors, the first, second, and third data lines being connected to different pixels, and a control line connected to a gate of the first transistor. - View Dependent Claims (21)
