Abstract
A waveform generator can be constructed at a small area size using thin-film transistors and generates multiple triangular-wave voltage waveforms different from one another in phase, and an image display device that applies the waveform generator. A waveform generator that uses loop-form resistive wiring is provided on a substrate. The waveform generator supplies a triangular-wave voltage waveform or stepped voltage waveform of a voltage signal occurring in the loop-form resistive wiring to pixel circuits. The loop-form resistive wiring has multiple voltage supply switches that supply at least two kinds of voltages.
