Abstract
Disclosed is a display device with a capacitive touch panel including a laminate between a display panel and a cover layer, the laminate having a viewing-side polarizing plate; a first conductive layer, a dielectric layer and a second conductive layer constituting a capacitive touch sensor; and a substrate, in which the first conductive layer, dielectric layer, second conductive layer, and substrate are positioned closer to the cover layer than is the viewing-side polarizing plate, the first conductive layer is formed on one surface of the to substrate, the dielectric layer is formed on a surface of the first conductive layer opposite to the substrate side, the second conductive layer is formed on a surface of the dielectric layer opposite to the first conductive layer side, the substrate has an optical film with a phase difference of (2n−1)λ/4, where n is a positive integer, the viewing-side polarizing plate has a polarizing film, and a slow axis of the optical film intersects a transmission axis of the polarizing film at an angle of about 45° as viewed in a stacking direction.
