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.

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 apparatus includes: a substrate comprising a first area overlapping an optical device and a second area surrounding at least a portion of the first area; a first insulating layer arranged on the substrate; a first pixel electrode and a second pixel electrode arranged apart from each other and disposed on the first area of the first insulating layer; a third pixel electrode and a fourth pixel electrode arranged apart from each other and disposed on the second area of the first insulating layer; and a second insulating layer arranged on the first insulating layer and defining first to fourth openings exposing the first to fourth pixel electrodes, respectively, where the second insulating layer further defines an auxiliary opening exposing a portion of the first insulating layer in the first area, and the auxiliary opening is located between the first opening and the second opening.
