ABSTRACT:
A liquid crystal display with a pixel matrix has a bias circuit for individually applying a bias voltage to color signals input to a pixel. By individually controlling the bias voltage applied to each color signal according to temperature, undesirable density or color change can be avoided. Further, a bias voltage can be applied to a common electrode and regulated in accordance with an integration of the voltage of a pixel so that the integration result becomes zero, to avoid production of a burning phenomenon.
