Abstract
Abstract A liquid crystal display including first and second translucent substrates opposed to each other, first and second transparent electrodes formed on the opposite faces of the first and second substrates, orientation films formed on the opposite faces so as to cover the first and second transparent electrodes, a liquid crystal filled in a space between the orientation films, the first electrode being divided into a plurality of dot electrodes arranged in the row and column directions, and the second electrode being divided into a plurality of stripe electrodes arranged opposite to the dot electrodes of the first electrode in the row direction, a first conductive film for serially connecting the dot electrodes in each column, and a second conductive film provided along the longitudinal edge of the stripe electrode, wherein the first and second substrates are positionally set such that the second conductive film is opposed to concave portions formed between the dot electrodes in the row direction.

Claim 1
Independent Claim
188 words
A liquid crystal display comprising: first and second transparent substrates opposed to each other, first and second transparent electrodes formed on the opposite faces of the first and second substrates, orientation films formed on the opposite faces so as to cover the first and second transparent electrodes, a liquid crystal filled in a space between the orientation films, the first electrode being divided into a plurality of dot electrodes arranged in the row and column directions and having concave portions and formed between the dot electrode in the row direction, and the second electrode being divided into a plurality of stripe electrodes arranged opposite to the dot electrodes of the first electrode in the row direction, a first conductive film for serially connecting the dot electrodes in each column, and a second conductive film providing a ridge along the longitudinal edge of each of the stripe electrodes, wherein the first and second substrate are positioned so that ridges formed by the second conductive film are opposite the concave portions formed between the dot electrodes in the row direction to reduce the possibility of electric contact between the substrates.
Claim 2
