REFLECTION TYPE ELECTRO-OPTIC DEVICE AND ELECTRO-OPTIC DEVICE

摘要

PROBLEM TO BE SOLVED: To increase a response speed and to stably fix the potential of pixels in respective pixels so as to prevent the drift of the level thereof by impressing a signal wavelength to a third signal line during the period when a signal waveform is impressed to a pair of first and second signal lines. SOLUTION: Liquid crystal potential VLC 14 attains the voltage VGG-Vth impressed to the first signal line 5 when the signal wavelength of on is impressed to the third signal line during the period when the signal waveform of on is impressed between a pair of the first signal line 5 and the second signal line 8. Also, the liquid crystal potential VLC 14 does not have the potential when the signal waveform of on is not impressed to the third signal line 3 during the period when the signal waveform of on or off is impressed between the first signal line 5 and the second signal line 8. The liquid crystal potential VLC 14 is given according to the voltage impressed to the third signal line 3 as described above and the voltage of the signal to be impressed to the signal line is varied, by which the potential difference to be applied to liquid crystals may be varied.
