Abstract: A display device includes a display panel including unit pixel areas and an input sensor including first-line elements and second-line elements defining crossing areas with the first-line elements. First group elements among the first-line elements and the second-line elements are electrically connected to each other to define a first electrode. Second group elements among the first-line elements and the second-line elements are electrically connected to each other to define a second electrode, and the second electrode is insulated from the first electrode while crossing the first electrode. A first angle defined by a first direction and a second direction and a second angle defined in the crossing areas by the first-line elements and the second-line elements to correspond to the first angle are different from each other.
