This invention relates to a suspension of a water-soluble, nonionic cellulose ether having a fairly low content of an electrolytic salt exhibiting a high stability and a low viscosity. The P and N doped regions can be parallel stripes or a mesh with each region being surrounded by doped material of opposite conductivity type. The n-type driving thin film transistor includes a second polycrystalline semiconductor pattern, a second gate electrode, a second source electrode and a second drain electrode.
