Abstract
Provided is an optical unit for a display panel device with a capacitive touch input function. In the optical unit, a touch panel laminate comprises: an optically transparent first substrate layer laminated to one surface of a transparent adhesive layer; a first transparent electrically conductive layer laminated, through a first undercoat layer, to a surface of the first substrate layer on a side opposite to the adhesive layer; an optically transparent second substrate layer laminated to the other surface of the adhesive layer; and a second transparent electrically conductive layer laminated, through a second undercoat layer, to a surface of the second substrate layer on a side opposite side to the adhesive layer.
