Abstract
A liquid crystal display device for carrying out a 3D display by a frame sequential method as well as a 2D display includes: a digital γ correction section for changing an input gray level to a gamma characteristic corresponding to either the 2D display or the 3D display in accordance with a preset analog gamma value; an overdrive circuit for finding, in accordance with a parameter set according to the gamma characteristic thus corrected by the digital γ correction section, an overdrive value corresponding to the input gray level; and an analog γ correction section for finding a voltage value to be applied to liquid crystal by correcting the overdrive value found by the overdrive circuit. In the digital γ correction section, an analog gamma value for the 3D display is set to be larger than an analog gamma value for the 2D display.
