Abstract
A liquid crystal display cell comprising a pair of flexible polymer film substrates having a transparent electrode disposed on the surface thereof and a liquid crystal material sandwiched therebetween. The transparent electrode is a metal oxide film which has a surface resistivity of not greater than 100 ohm per square, a bending property of not greater than 2.0, a curling degree, H, of 0<H<5 mm and a transmittance to light of 550 nm of not less than 75%. Further, this metal oxide is substantially amorphous, and is formed by a DC sputtering method.
