1. A liquid crystal display apparatus comprising:
a liquid crystal display panel comprising a matrix array of transistors and a matrix array of liquid crystal cells respectively connected to said transistors, said transistors being respectively connected to intersections of a plurality of column lines and a plurality of row lines for respectively activating the liquid crystal cells; and
a driving circuit for successively generating a plurality of write-in voltages, successively selecting each of said row lines and supplying said write-in voltages from end points of the column lines to the liquid crystal cells of the selected row line for a period corresponding to a distance from the selected row line to said end points; wherein said period corresponding to a distance increases as a function of the distance from the selected row line to said end points.
