  • Patent number: 8289489
    Abstract: Provided are a fringe-field-switching (FFS)-mode liquid crystal display (LCD) and a method of manufacturing the same. The FFS-mode LCD includes a transparent common electrode, a conductive reflection structure electrically connected to the transparent common electrode, and a transparent pixel electrode formed on the conductive reflection structure and including a plurality of slits. The transparent common electrode is formed on a region including a data line and a gate line so that respective unit pixel regions can be electrically connected to one another.

  • Patent number: 6466287
    Abstract: Disclosed is a method for forming a reflector of a reflective LCD capable of improving a viewing angle characteristic while simplifying a forming process, the method comprising the steps of: applying a photoresist film on an insulating substrate; dispersing a plurality of spacers over a surface of the photoresist film; curing the photoresist film; rubbing the spacers-dispersed and cured photoresist film, thereby removing the spacers; and performing a vapor deposition of a metal film having a high reflectivity on the photoresist film.
