Patent ID: 7636144

Claim:
A liquid crystal display device comprising: a pair of transparent substrates sandwiching a liquid crystal layer; one of the pair of transparent substrates on the liquid crystal layer side being provided with: a plurality of scan lines and a plurality of signal lines disposed in a matrix in a display region; a switching element provided near an intersection of the plurality of scan lines and the plurality of signal lines; a common line formed along a periphery portion of the display region; a planarization film formed over at least the whole display region; a first electrode formed on a surface of the planarization film; an insulator formed on the first electrode; and a second electrode formed on the insulator and having a plurality of slits for each position corresponding to a region divided by the plurality of scan lines and the plurality of signal lines; the second electrode being electrically connected with the common line or the switching element via a first contact hole formed on the insulator and the planarization film; the first electrode being electrically connected with the switching element or the common line, different from the common line or the switching element with which the second electrode is electrically connected, via an interface-structured conductive path, formed of a material used for forming the second electrode, formed via a second contact hole on the insulator, a surface of the insulator, and a third contact hole formed on the insulator and the planarization film.
