Abstract: A display device includes: a display panel; and an inspection circuit at a non-display area. The display panel includes: first data lines at a display area; first connection lines at the non-display area; second data lines at the display area; and second connection lines at the non-display area. The inspection circuit includes: first transistors to be controlled by a first inspection signal of a first inspection line; second transistors to be controlled by a second inspection signal of a second inspection line; third transistors to be controlled by a third inspection signal of a third inspection line; fourth transistors to be controlled by a fourth inspection signal of a fourth inspection line; fifth transistors to be controlled by a fifth inspection signal of a fifth inspection line; and sixth transistors to be controlled by a sixth inspection signal of a sixth inspection line.

Abstract: A display device includes a first pixel row, a first first-structure transmission line, a first second-structure transmission line, a first transistor, and a second transistor. The first pixel row includes a first first-color sub-pixel and a second first-color sub-pixel both for displaying a first color. The first second-structure transmission line neighbors the first first-structure transmission line with no intervening transmission line analogous to the first first-structure transmission line or the first second-structure transmission line being disposed between the first first-structure transmission line and the first second-structure transmission line. The first transistor is electrically connected through the first first-structure transmission line to the first first-color sub-pixel and receives a first test voltage. The second transistor is electrically connected through the first second-structure transmission line to the second first-color sub-pixel and receives a second test voltage different from the first test voltage.

Abstract: A display device includes: a display area including a plurality of pixels arranged to have a non-uniform horizontal resolution in a first direction; a peripheral area extending around the display area; a circuit area at a side of the peripheral area; a first main crack detection line in the peripheral area and extending along a first edge of the peripheral area; a first switching element in the circuit area and connected to a first end of the first main crack detection line; and a first data line connected to the first switching element and extending in a second direction that is different from the first direction through the display area. Twice a distance between the first data line and a center of the display area is equal to or greater than a length of the first data line in the second direction.
