ABSTRACT:
A liquid crystal display device according to the present invention includes a liquid crystal panel having a vertical alignment type liquid crystal layer, and a drive circuit for supplying a driving voltage to the liquid crystal panel, and performs display in a normally black mode. At least at panel temperature 40° C., a rise transmittance Tr is equal to or greater than 75% of the transmittance in the highest gray scale level displaying state, and a decay transmittance Td is equal to or less than 8% of the transmittance in the highest gray scale level displaying state. At a panel temperature T1below 40° C., the decay transmittance Td is greater than 4% and equal to or less than 8% of the transmittance in the highest gray scale level displaying state, and when displaying an intermediate gray scale level which is higher than a gray scale level displayed in a previous vertical scanning period, the drive circuit supplies an overshoot voltage OSVT1which is lower than a just overshoot voltage JOSVT1for the panel temperature T1.
