Abstract

A display device includes a display panel including light-emitting regions, an input sensor, and conductive patterns. The conductive patterns include a first sensing electrode including first sensing patterns provided along a first direction, and bridge patterns connecting two adjacently disposed first sensing patterns, a second sensing electrode, spaced apart from the first sensing electrode, includes second sensing patterns provided along a second direction crossing the first direction, and dummy patterns overlapping one of the first sensing electrode or the second sensing electrode on a plane. Each of the first sensing patterns and the second sensing patterns includes mesh lines in which openings overlapping the light-emitting regions are defined. Each of the bridge patterns includes a first bridge pattern connected to a corresponding first sensing pattern, and a second bridge pattern disposed on a layer different from the first bridge pattern, and connected to the first bridge pattern.
