Abstract
A display device includes a display panel in which signal wirings are arranged, and a first circuit board attached to the display panel. The first circuit board includes a lead wiring layer including first lead wirings, an organic protective layer on the lead wiring layer and partially exposing the first lead wirings, and an anisotropic conductive film between the lead wiring layer and the organic protective layer and electrically connecting the exposed first lead wirings to the signal wirings. A side surface of the organic protective layer, facing a side surface of the display panel, is spaced apart from the side surface of the display panel, and the anisotropic conductive film is disposed in a space between the exposed first lead wirings and the side surface of the organic protective layer and a space between the exposed first lead wirings and the side surface of the display panel.
