Abstract: A display device includes: a substrate including a display area, and a non-display area defined around the display area, a driver disposed in the non-display area on the substrate, first crack detection lines disposed in the non-display area on the substrate, where a part of each of the first crack detection lines adjacent to an end of the driver extends in parallel with an edge of the substrate, a second crack detection line disposed in the non-display area on the substrate, electrically connected to the first crack detection lines, and positioned between the first crack detection lines and the driver, and a common voltage line disposed in the non-display area on the substrate. A concave portion overlapping at least a part of the second crack detection line in a plan view is defined at an edge portion of the common voltage line facing the first crack detection lines.

Abstract: A display substrate includes a base substrate, a switching device, and a pixel electrode including a first sub pixel electrode and a second sub pixel electrode. The first sub pixel electrode includes an internal electrode and an external electrode. The internal electrode includes a support electrode portion extending in a second direction, and a horizontal internal branch electrode portion extending in a first direction. The external electrode includes a horizontal external branch electrode portion disposed outside the internal electrode and extending in the first direction, and a vertical external branch electrode portion disposed outside the internal electrode and extending in the second direction. The second sub pixel electrode is adjacent to the first sub pixel electrode and has a shape symmetrical to the first sub pixel electrode.

Abstract: A display device includes a display panel that includes a first area and a second area that surrounds at least a portion of the first area. The display panel includes a base layer, a display element layer disposed on the base layer in the second area, an encapsulation layer disposed on the display element layer and that includes an opening portion that corresponds to the first area and an inclined portion that has a height that decreases with decreasing distance from the opening portion, and an inclination compensation layer that is disposed on the inclined portion and does not overlap the opening portion.
