A liquid crystal display device includes: pixel electrodes arranged in columns and rows, each including a reflective electrode region; scanning lines; and signal lines. The device sequentially supplies a scanning signal voltage to one of the scanning lines after another to select one group of pixel electrodes, connected to the same one of the scanning lines, after another, and then supplies display signal voltages to the selected group of pixel electrodes by way of the signal lines, thereby displaying an image thereon. The pixel electrodes are arranged such that the polarity of a voltage to be applied to a liquid crystal layer is inverted for every predetermined number of pixel electrodes in each of the rows and in each of the columns. The display signal voltage to be supplied to each pixel electrode is updated at a frequency of 45 Hz or less.

An anti-skid apparatus for installation in a vehicle braking system having a regulator valve for producing a hydraulic power pressure in accordance with a hydraulic braking pressure from a master cylinder. A control cylinder is disposed in a hydraulic circuit connecting the master cylinder to a wheel brake cylinder, and comprises a cylinder body having a cylinder bore defined therein and a piston axially slidably disposed within the cylinder bore. This piston forms at its one end a pressure chamber communicating with the wheel brake cylinder, and is applied at its the other end with the hydraulic power pressure from the regulator. Disposed in the control cylinder is a normally open cut-off valve which normally permits the flow of the hydraulic braking pressure from the master cylinder into the pressure chamber and blocks the flow of the hydraulic braking pressure when the piston moves to an extent more than a predetermined distance from its initial position for decreasing the volume of the pressure chamber. And, a changeover valve is disposed between the regulator valve and the control cylinder, and applies the hydraulic power pressure to the piston or discharges it from the control cylinder.
