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.
