Abstract: An electronic device includes a display unit having a plurality of pixels. Each of the pixels includes a transistor and a light-emitting element. A plurality of signal lines is connected to the pixels. An encapsulation layer covers the pixels. The display unit includes a display region and a non-display region adjacent to the display region in a plan view. A sensing unit includes a plurality of sensing patterns overlapping the display region. A plurality of sensing pads overlaps the non-display region. A plurality of sensing lines electrically connects the sensing patterns and the sensing pads. A bridge line is connected to a first sensing line and a corresponding first sensing pad. The bridge line is bent to extend in a direction that is different from an extending direction of the first sensing line to connect the bridge line to the first sensing pad.
