US 5,515,191 A · Liquid crystal display having enhanced conductors and adhesive spacers

Abstract

Briefly, according to the invention, there is provided a liquid crystal display device (LCD). The LCD has an electrode pattern (14) deposited on one side of a substrate (10). The pattern is formed in a series of elements or pixels (13), that are arranged in a regularly ordered matrix of rows and columns. Metal conductors (16) are also on the face of the substrate and are electrically connected to the electrode elements. A spacer material (27) is formed on metal conductors and a second substrate (10') is placed on the first substrate, and the two substrates are arranged so that a uniform gap (25) is maintained between the substrates by the spacer material. A liquid crystal material (29) is then disposed in the uniform gap. The spacer material can be a photoimaged adhesive, the electrode pattern can be indium/tin oxide, the metal conductors can be copper, and the metal conductors are located between the rows and columns of the plurality of elements in the electrode pattern.
