Abstract
An active-matrix display device having low-resistance added capacitance electrode wires in which single or plural secondary wires connected electrically to the added capacitance electrode wires reduce the apparent electrical resistance of the added capacitance electrode wires, which makes the time constant of the added capacitance electrode wires smaller, so that the charging characteristics of the added capacitance are improved and contrast and other display characteristics of the liquid crystal display device are improved.
