Abstract

See full text

An image signal with a magnitude in accordance with a tone to be displayed is supplied to pixels via data lines in a tone display period, and a precharge voltage including a low-potential second voltage and a high-potential second voltage is supplied to the data lines in a precharge period before the tone display period. Control is made such that a first pattern in which the low-potential second voltage and the high-potential second voltage are sequentially output in the precharge period in one horizontal scanning period and a second pattern in which only the high-potential second voltage is output in the precharge period in one horizontal scanning period are switched in accordance with a selected scanning line. Also, control is made such that a supply period of the high-potential second voltage in the second pattern is shorter than a supply period of the high-potential second voltage in the first pattern.
