Abstract

An exemplary display device providing touch function includes scanning lines and data lines thereby defining lots of sub-pixel units. Each sub-pixel unit includes a pixel electrode, a storage capacitor, a compensation capacitor connected between the pixel electrode and a corresponding scanning line. In each pixel unit defined by n number adjacent sub-pixel units, both of a ratio of capacitance values between the storage capacitors formed in the corresponding sub-pixel units and a ratio of capacitance values between the corresponding compensation capacitors are respectively substantially equal to a ratio of areas between the corresponding pixel electrodes.
