Patent ID: 8755011

Claim:
A liquid crystal display device comprising: (a) a first transparent substrate; (b) a second substrate spaced away from and facing said first transparent substrate; and (c) a liquid crystal layer sandwiched between said first transparent substrate and said second substrate, wherein said first transparent substrate has a first area through which a light is allowed to pass and a second area in which a light is reflected, a reflection electrode is formed in said second area, said reflection electrode being comprised of an underlying film formed on an electrically insulating film and composed of one of molybdenum, chromium, titanium and tantalum, and an overlying film formed on said underlying film and composed of one of aluminum and silver, a transmission electrode is formed on said electrically insulating film in said first area, an end part of said reflection electrode partially overlaps an end part of said transmission electrode such that said reflection electrode is located on said transmission electrode, said electrically insulating film is an organic film, said underlying film has a thickness in the range of 100 to 3000 angstroms, said overlying film has a thickness in the range of 500 to 5000 angstroms, said overlying film is not located on an edge of the underlying film on the transmission electrode, and a distance between an edge of the overlying film and the edge of the underlying film in a direction parallel to the first transparent substrate is equal to or greater than 1.0 micrometers.
