摘要： A display device with a capacitive touch panel includes a laminate between a display panel and a cover layer, the laminate having a circularly polarizing plate, a first conductive layer, and a second conductive layer. The circularly polarizing plate includes a substrate and a polarizing plate. The first conductive layer, the second conductive layer, and the substrate are positioned closer to the display panel than is the polarizing plate, and the first conductive layer is positioned closer to the cover layer than is the second conductive layer. The first and second conductive layers are arranged apart from each other in a stacking direction so as to form a capacitive touch sensor. One of the first and second conductive layers is formed on one surface of the substrate. The substrate has an optical film with a phase difference of λ/4. The polarizing plate has a polarizing film.
