Abstract:
An improved touch panel with a polarizer integrally formed therein, which comprises a touch panel including an upper substrate having an upper sheet and a transparent conductive film formed below said upper sheet, a lower substrate having a transparent conductive film like said transparent conductive film of said upper substrate and a lower sheet formed below said transparent conductive film, dot spacers for insulating said upper and lower substrates from each other, and electrodes for applying voltage to a resistive film disposed between said upper and lower sheets; and a polarizer bonded to said lower sheet of said touch panel for converting visual light to linearly polarized light, the improvement comprising:said dot spacers formed between said respective transparent conductive films of said upper and lower sheets are formed on said lower sheet so that said upper and lower substrates are laminated to each other; said polarizer sequentially having an upper base, an optical film base and a lower base; an adhesive layer, which is bonded together to said lower sheet of said touch panel and causes said polarizer to be integrated with said touch panel in order to manufacture a laminate structure of said touch panel, is provided on an upper face of said upper base of said polarizer; and another adhesive layer for causing said polarizer incorporated into said touch panel to be bonded to an upper glass sheet of a liquid crystal display device, is provided on a lower face of said lower base of said polarizer.
