ABSTRACT:
A color image display includes: a liquid crystal cell having a light transmittance varying according to a potential at a data holding node; a scan circuit applying one of first and second potentials to the data holding node in accordance with an image signal; and a refresh circuit refreshing potential at the data holding node to a first potential in response to a refresh signal when the potential at the data holding node exceeds a threshold potential of an N-type TFT, and not refreshing the potential at the data holding node when the potential at the data holding node does not exceed the threshold potential.
