Liquid crystal electro-optic device

摘要

In a horizontal electric field drive type liquid crystal electro-optic device, a gate electrode, a source electrode, a drain electrode, a semiconductor film and a common electrode are formed on a glass substrate and a liquid crystal material is driven by controlling the strength of an electric field substantially parallel to the glass substrate. The electrodes and the semiconductor film are made curved, for example semi-circular or semi-elliptical, in sectional profile. These curved sectional profiles can be formed by suitably selecting and combining various patterning and etching methods.
