Abstract
A method of driving a liquid crystal display element that applies an AC pulse voltage to drive liquid crystal includes: when the temperature of the liquid crystal is higher than a reference temperature, generating the AC pulse voltage for high temperature having a pulse width that is shorter than a reference pulse width of a reference AC pulse voltage used at the reference temperature; and applying the generated AC pulse voltage to the liquid crystal in a period that is equal to the reference pulse width.
