Patent ID: 8023088

Claim:
A liquid crystal display device comprising: a liquid crystal layer; and a pair of transparent substrates that enclose the liquid crystal layer; wherein the liquid crystal layer face of one of such pair of transparent substrates being provided with: multiple scan lines and signal lines that are formed in matrix layouts in a display area; switching elements that are provided near intersections of the multiple scan lines and signal lines; a first insulator that covers surfaces of the switching elements; a planarization layer that is formed over the entire surface of the display area; first electrodes, and second electrodes with multiple slits, that are constituted of transparent electrically conductive material that are disposed opposing each other on the planarization film with a second insulator interposed; and lower wires that are constituted of the same material as the scan lines formed at peripheral portions of the display area, and upper wires that are constituted of the same material as the signal lines formed at peripheral portions of the display area; wherein the switching elements being covered by the first insulator and moreover the upper wire being covered by the second insulator; a connection-switching line for electrically connecting the lower wire and the upper wire; wherein the connection-switching line being formed from transparent conductive material of the same composition as the second electrodes, and moreover extending over the surface of the second insulator and electrically connecting the upper wire and the lower wire via second contact holes formed in the second insulator laid over the upper wire and third contact holes formed in the first and second insulators laid over the lower wire.
