れている。2. Description of the Related Art Liquid crystal display devices that display by utilizing the orientation of liquid crystals have been used from the initial display of simple numbers and symbols such as clocks and calculators to the recent high-definition image display such as televisions. In particular, in the case of a liquid crystal display device, a small device such as a portable TV is expected because the screen can be made thin.

要な要素となる。The first requirement for a mobile device such as a portable television is that it be lightweight. In electric equipment, it is not uncommon for a power source such as a battery to drive the electric equipment to occupy most of the weight in particular, and it is a very important factor that the power consumption is as small as possible and a low-capacity power source can be driven for a long time.

振幅を半分に抑えた駆動手段が挙げられる。However, in the case of the conventional liquid crystal display device using the TN liquid crystal, in order to prevent the phenomenon called sticking peculiar to the liquid crystal panel and improve the reliability, the potential applied to the pixel is inverted at regular intervals. Was normal. Normally, the TN liquid crystal is driven by 0 to 5V, but in order to perform this inversion, ± 5V with respect to the common electrode of constant potential,
That is, it is necessary to input a signal having an amplitude of 10 V, and the power consumption is doubled. As a means for solving such a problem, for example, as disclosed in JP-A-58-49989 and JP-A-60-163091, the potential of the counter electrode is inverted between positive and negative. There is a driving means whose amplitude is reduced to half.

Further, since it is common to the control means of the gate of the transistor of the driving circuit, a large number of wirings are required between the upper and lower substrates, the manufacturing process is complicated, the yield is low, and the reliability of the device is low.
