Abstract

A polarizer integrated with a transparent conductive film for a liquid crystal display includes a lower film an optical film and a transparent conductive film. A touch panel integrated with the polarizer is formed by attaching an upper sheet to the upper surface of the polarizer integrated with a transparent conductive film. A flat panel display with an integral type touch panel includes a touch panel integrated with the flat panel display having a lower polarizer, a liquid crystal display and an upper polarizer.

Claims

1. A polarizer integrated with a transparent conductive film comprising:

a lower film;

an optical film over the lower film; and

the transparent conductive film over the optical film.
