Abstract: PURPOSE:To efficiently shift the threshold voltages of the thin film transistor matrix of a gate connection type in a short period of time by applying the voltages which change stepwise in every one stage over a prescribed number of steps to respective scan buses while shifting the voltages by each one step between the respective two adjacent scan buses. CONSTITUTION:The voltages which change stepwise in over plural steps in each one step as time passes by are impressed successively between the adjacent scan buses by shifting the voltages in phase by each one step. The voltages to be impressed between the gate and drains of the respective TFTs are, therefore, the repetition of the period A when the positive high voltage nEXVE is impressed and the period B when the negative low voltage -VE is impressed where the number of the lines of the scan buses SB is designated as N, the number of steps of the stair-like waveform of the impressed voltage as nE and the voltage per step as VE. The required time, therefore, decreases to (nE+1)/N and the required max. voltage decreases to 1/N. The threshold voltages of the thin-film transistor matrix of the gate connection type are shifted efficiently in this way in a short period of time.
