KR970016728A - Manufacturing method of ferroelectric liquid crystal display - Google Patents

Abstract

In order to solve the structural defects of the ferroelectric liquid crystal display, transparent electrodes, spacers and alignment films are sequentially formed on the glass substrate, and then the liquid crystal film is formed by vacuum deposition, and the respective liquid crystal devices are bonded to each other. The phase change of the bonded liquid crystal film of the isotropic phase to the ferroelectric liquid crystal of the Simexic C ^* phase to complete the liquid crystal display can remove the structural defects occurred in the conventional liquid crystal display.
