Abstract: A liquid crystal display apparatus switches modes from a normal display mode to a stop preparation mode when a main power source voltage drops. In the display mode, a gate drive circuit sequentially applies a first gate-on pulse to gate bus lines so as to select pixel rows sequentially, and applies a second gate-on pulse to buffer capacitor scanning lines, each of which is associated with a pixel row selected by the first gate-on pulse, during a period that does not overlap a period during which the first gate-on pulse is applied, and a source drive circuit applies a display signal voltage to source bus lines.

Abstract: A disclosed liquid-crystal display apparatus comprises a display panel comprising a plurality of pixels, a plurality of scanning lines, and a plurality of data lines; and an image signal correction unit to correct a grayscale value determined in accordance with the transmittance the pixel is to have. The image signal correction unit carries out a first correction to bring a first grayscale value farther away from a second grayscale value by a first correction amount determined based on the state of difference between the first grayscale value determined in accordance with the transmittance a first pixel is to have and the second grayscale value determined in accordance with the transmittance a second pixel selected following the first pixel is to have. The first correction is a correction for bringing the transmittance of the first pixel closer to the transmittance according to the first grayscale value.
