Abstract
A polarizer, having touch sensing capability includes a polarizing layer, a transparent conducive layer, and first driving-sensing electrodes. The transparent conducive layer and the polarizing layer are stacked with each other. The transparent conductive layer is an anisotropic impedance layer having a relatively low impedance direction and a relatively high impedance direction. The first driving-sensing electrodes are spaced with each other and arranged in a row along the relatively high impedance direction and electrically connected with the transparent conducive layer.
