Abstract
A display unit comprises a transparent touch switch and a liquid crystal display having a display surface. At least an input area of the transparent touch switch is laminated to the display surface of the liquid crystal display by clear adhesive. The clear adhesive has a permeability after hardening which is close to the permeability of the liquid crystal display and the transparent touch switch. Clear fillers are disposed in the clear adhesive to prevent warping of the transparent touch switch and the liquid crystal display.
