Abstract

A touch panel has a reduced whole thickness when attached to a display device, increases the accuracy of the positional information, and improves the display quality and durability inexpensively. One of a pair of resistive layers facing each other across insulating dot spacers is laid on a light-transmissible flat plate formed of a PET film rather than a glass plate, and a light conductive plate of a front light unit is integrated with an outer surface of the light-transmissible flat plate. An AR film having a transparent gel layer is disposed between the PET film and the light conductive plate. The transparent gel layer is of a gel material such as silicone rubber and is applied integrally on the AR film, which is formed such that anti-reflection treatment is applied on a surface of a base material of a FET film.
