A driving method of a matrix type liquid crystal display element including at least JxL (J and L are respectively integers of 2 or more) row electrodes and a plural number of column electrodes wherein the JxL row electrodes are divided into J row electrode subgroups each including n row electrodes so that the subgroups are selected as each batch to be driven. When voltages are applied to the row electrodes, either a voltage level of +Vr or -Vr (where Vr>0) is applied at a selection time, when a voltage at a non-selection time is 0 (zero). Voltages applied to the column electrodes are selected from (L+1) voltage levels of V0, V1, . . . , VL (where V0<V1 . . . <VL), and when a two-valued information of the j-th line electrode subgroup (j is an integer of any of 1 through J) in a specified column in the plural column electrodes is expressed by a column vector Dj having L elements (where the elements of the vector Dj include 1 indicating ON and 0 indicating OFF), specific conditions must be satisfied.
