Abstract: A display device includes a display panel that includes a display region on which a pixel is disposed and a non-display region around the display region. An input sensor is disposed on the display panel and is configured to detect an electromagnetically induced current. A conductive layer is disposed below the display panel and overlaps the display region. The conductive layer includes a first unit pattern. The first unit pattern includes a first extension part, and a plurality of second extension parts that extend from the first extension part in a direction intersecting a direction of the first extension part and are disposed on one side of the first extension part.
