Abstract
A display panel device has a window, a touch panel laminate and a display panel. The touch panel laminate has: a transparent first substrate layer; a first transparent conductive layer laminated to the first substrate layer through a first undercoat layer; a transparent second substrate layer; and a second transparent conductive layer laminated to the second substrate layer through a second undercoat layer. The second conductive layer faces the first conductive layer through at least the first substrate layer and the first undercoat layer. The first conductive layer is closer to the window than the first substrate layer. A polarizing film layer is bonded to the window, and a λ/4 retardation film layer is disposed between the polarizing film layer and the touch panel laminate. The display panel is disposed on a side opposite to the window with respect to the touch panel laminate.
