Abstract
In a liquid-crystal display device of active matrix type, a plurality of column-selecting lines and a plurality of auxiliary capacitance lines are formed on a transparent substrate. A plurality of row-selecting lines and two display-electrode segments are formed on an insulative film formed on the column-selecting and auxiliary capacitance lines and the transparent substrate. Two switching elements each connected to the column-selecting, row-selecting and auxiliary capacitance lines are also formed on the transparent substrate. Two auxiliary capacitors are formed between the display-electrode segments and the auxiliary capacitance line. A strip conductor is formed on the transparent substrate under each pair of display-electrode segments. A common electrode opposes the display-electrode segments with a liquid crystal layer therebetween.
