Abstract
A high-density N-type diffusion layerformed in a separation areamakes it possible to reduce a collector current flowing through a parasitic NPN transistor. Thus, a normal CMOS process can be used to provide a driving circuit and a data line driver which make it possible to improve resistance to possible noise occurring between adjacent terminals, while controlling a chip size.
