A MVA type liquid crystal panel is slow in a response speed when a black
state at a drive voltage about 1V is switched to a low brightness
halftone state at the drive voltage about 2 to 3V. According to the
present invention, in a liquid crystal display device for driving the MVA
type liquid crystal panel, when a liquid crystal pixel at a pixel
electrode is changed from a first transmittance to a second transmittance
greater than the first transmittance, a drive voltage greater than a fist
target drive voltage in correspondence with a second transmittance is
applied to the pixel electrode in a first frame period of changing to the
second transmittance, and the first target display voltage is applied
from a second frame period. According to the present invention, even when
either switching is performed from a black state to a low brightness
halftone state, from the black state to a high brightness halftone state,
for from the black state to a white state, a response time is shortened,
and the switching can be performed without generating an overshoot.
