Patent ID: 7369200

Claim:
A liquid crystal display comprising a lower substrate on which interconnections and thin film transistors are formed; an opposite substrate so arranged as to face said lower substrate; a liquid crystal layer sandwiched between said lower substrate and said opposite substrate; a reflection electrode formed in a reflection area of said lower substrate; a transparent electrode formed in a transparent area of said lower substrate; and a common electrode formed on said opposite substrate; wherein an insulating layer is deposited on said thin film transistors, said reflection electrode and said transparent electrode are formed directly on said insulating layer at predetermined regions, said transparent electrode is electrically connected to a source electrode of each of said thin film transistors via a contact hole formed in said insulating layer, said opposite substrate is electrically connected to said transparent electrode and an insulating film is deposited on that surface of said opposite substrate which contacts said liquid crystal layer, and a drive circuit for applying a voltage between said reflection electrode and said transparent electrode and said common electrode, whereby a potential difference between a drive voltage applied to that surface of said lower substrate which contacts said liquid crystal layer and a drive voltage applied to that surface of said opposite substrate which contacts said liquid crystal layer is made lower in said reflection area than in said transparent area.
