Abstract

There is provided a touch panel for a display device for reducing the whole thickness thereof when the touch panel is attached to the display device, increasing the accuracy of the positional information and improving the display quality and the durability thereof. One resistive layer of a pair of resistive layers disposed opposite to each other across a plurality of insulating dot spacers is laid on a translucent flat plate, and a light conductive plate of a front light unit is integrated with an outer surface side of the translucent flat plate. The translucent flat plate is formed of a PET film in place of a glass plate.
