Title:
液晶表示装置、駆動方法および電子機器
Document Type and Number:
Japanese Patent JP5370021
Kind Code:
B2
Abstract:
A liquid crystal display device includes: pixel that corresponds to intersection of scanning line and data line and that each change the transmittance or reflectance of a liquid crystal element by means of a pair of electrodes; a scanning line driving circuit that selects scanning line and applies a selection voltage to the selected scanning line; and a data line driving circuit that applies writing voltages through the data line to the pixel that corresponds to the selected scanning line, wherein the scanning line driving circuit applies the selection voltage to the selected scanning line for video signal writing periods and setting periods that start before the video signal writing periods, respectively, the data line driving circuit supplies, to the pixel, data signals with voltages corresponding to video signals for the video signal writing periods and supplies, to the pixel, a setting signal with a predetermined voltage for the setting periods, and each of the setting periods is shorter than a response time required for the transmittance or reflectance of each of the liquid crystal element to change from 0% to 100% or a response time required for the transmittance or reflectance of each of the liquid crystal element to change from 100% to 0%.
