Abstract: A display device includes a display panel including first, second, and third emissive regions and an input sensing layer. The input sensing layer is disposed on the display panel and includes sensing parts. The sensing parts include first, second, and third openings that overlap the first, second, and third emissive regions, respectively, and a cut-away portion that connects the first opening and the second opening. A cut width A of the cut-away portion satisfies Inequality 1:

Abstract: A display module includes a display panel having a display region in which pixels are disposed and a non-display region having a first pad region in which first signal pads, electrically connected to the pixels respectively through first signal lines, are disposed. An input sensor is disposed on the display panel and it includes a sensing insulation layer including an organic material, and a sensing conductive layer. Each of the first signal pads includes first conductive patterns stacked along a thickness direction of the display panel. At least one of the first conductive patterns includes a same material as that of the sensing conductive layer. A first opening overlapping the first pad region is defined in the sensing insulation layer. A first residue conductive pattern, including the same material as that of the sensing conductive layer, is disposed on a border of the first opening.
