Abstract
A polarizing device has a polarizing layer, a first protection layer, a second protection layer, a conductive layer, an insulating layer, an electrode layer and a hardening coating layer. When a user touches a monitor, which is implemented with the polarizing device, by his/her finger, the coordinate of the touch point will be detected by monitoring the interference caused on the equivalently generated electric filed.
