20130284350 | MANUFACTURING METHOD OF LIQUID CRYSTAL DISPLAY DEVICE - An ultraviolet-curable resin is formed over a touch panel, and a liquid crystal display panel is bonded to the touch panel. Subsequently, an ultraviolet-curable resin is formed over the touch panel, and a front window is bonded to the touch panel.
