Plastic liquid crystal display device and method for manufacturing the same

Abstract

A plastic liquid crystal display device and a fabrication method thereof. A plastic substrate having a plurality of bumps on at least one surface thereof is integrally molded. A glass transition temperature (T g ) of the plastic substrate is greater than 150° C. A melt flow index (MFI) of the plastic substrate is greater than 2. A conformal reflective film on the plastic substrate with the bumps is formed. An insulating substrate opposite the plastic plate is provided. A transparent electrode is formed on an inner surface of the insulating substrate. A liquid crystal layer is inserted between the plastic substrate and the insulating substrate.
