Abstract
The display device having a touch panel includes a detection electrode forming a touch panel and arranged on one surface of a display cell, a protective layer covering the detection electrode, and an optical film adhered to the protective layer, wherein a first surface of the protective layer adjacent to the optical film has a smaller water contact angle compared to a second surface of the protective layer adjacent to the display cell. The first surface of the protective layer is preferred to have a half or less the water contact angle compared to the second surface of the protective layer.
