1. A liquid crystal display device comprising:
- a first substrate and a second substrate;
a plurality of liquid crystal cells disposed between said first and second substrates;
a polarized disposed on said first substrate on a side opposite said plurality of liquid crystal cells;
an electrically conductive film, disposed between said polarizer and said first substrate, for detecting position of an input device based upon signals applied to said film, said electrically conductive film being directly applied to said polarizer, wherein said film is continuous between edges of one of said polarizer and said first substrate, and a linearization pattern is formed on an outer peripheral region of said electrically conductive film.

Abstract
The present invention provides a liquid crystal display device having a position detecting function with a high sensitivity and a high resolution. The position detecting function comprises a position detecting electrically conductive film on a polarizer or a color filter glass substrate of the liquid crystal display device. The present invention also can suppress the undesired generation of an air gap between the polarizer and color filter glass substrate by using a polarizer that is smaller in size relative to the position detecting electrically conductive film.
