Abstract

A display device includes a display panel and an input sensor. The input sensor may include a first detection pattern, and a first detection electrode including a bridge pattern electrically connected to the first detection pattern. The bridge pattern may include a (1-1)-th conductive layer, and a (1-2)-th conductive layer, and the first detection pattern may include a (2-1)-th conductive layer, and a (2-2)-th conductive layer. A first opening portion that exposes the one surface of the (1-1)-th conductive layer may be defined in the (1-2)-th conductive layer, and a second opening portion that exposes the one surface of the (2-1)-th conductive layer may be defined in the (2-2)-th conductive layer. The one surface of the (1-1)-th conductive layer and the one surface of the (2-1)-th conductive layer may be in contact with each other.
