Abstract
PURPOSE: To prevent the life of liquid crystal from being shortened even in the case dispersion is generated in the characteristic of a thin film transistor by dividing a transparent electrode at the display part of an upper transparent base plate to some parts and applying different DC voltage to the respective parts so that the display of an entire screen may be optimum. CONSTITUTION: The upper transparent base plate 1 is divided to small parts, and the optimum DC voltage is applied to the respective parts. For example, in the case the dispersion of the characteristic of the thin film transistor has concentric distribution depending only on a distance from the center of the base plate 1 where the thin film transistor, etc., are formed and voltage waveform different from each other is outputted, the DC voltage in accordance with the voltage waveform is applied to the transparent electrodes 2 to 4 so as to optimize the voltage impressed on the liquid crystal. Thus, the life of the liquid crystal is improved even in the case of using the base plate 1 where the dispersion is generated in the characteristic of the thin film transistor.
