PURPOSE:To provide a uniform display without the unevenness in the display by impressing the prescribed correction voltage corresponding to the voltage to be impressed to signal electrodes of a liquid crystal panel to the scanning electrodes to be non- selected among the scanning electrodes of the liquid crystal panel. CONSTITUTION:The rising characteristic of the scanning voltage changes in the case in which the signal voltage attains selection voltages V0, V5 and attains non-selection voltages V2, V3 in the driving voltage when converted to the AC of one scanning period of the scanning voltage and signal voltage of the liquid crystal panel. More specifically, the distortion in the waveform of the voltage to be impressed to the liquid crystal layer can be corrected by changing the rising characteristic of the scanning voltage. The driving of the actual liquid crystal panel is performed in an ideal state with substantially no distortions in the waveform of the driving voltage. The unevenness in the display which depends on display patterns is decreased by the method for correcting the voltage on the scanning side and the liquid crystal panel having the good display uniformity is obtd. Furthermore, the display contrast is improved, since the voltage of the effective values of on and off can be corrected to correct values.
