A display device includes a display module including a display panel and an input sensing layer on the display panel, and a flexible circuit film connected to the display module. The flexible circuit film includes a base film, a sensor connection wire, a ground wire, an insulating layer, a first conductive layer, and a cover tape. The sensor connection wire is on the base film and is electrically connected to the input sensing layer. The ground wire is on the base film, and the insulating layer covers the sensor connection wire. The first conductive layer is on the insulating layer and is electrically connected to the ground wire, and the cover tape is on the first conductive layer and is electrically connected to the ground wire.
