Patent ID: 7961282

Claim:
A liquid crystal display device having a display panel in which an annular sealing material is arranged between a pair of substrates, a liquid crystal material is sealed in a space surrounded by the pair of substrates and the sealing material, a display region is formed in the inside of a region surrounded by the sealing material in a plan view, and signal lines which extend to the outside of the sealing material from the inside of the display region is formed on one of the substrates, wherein the pair of substrates have orientation films on surfaces thereof which face opposing substrates, the substrate on which the signal lines are formed, on a side thereof which is disposed between a region on which the sealing material is arranged and the display region and along which the signal lines extend to the outside of the sealing material from the display region, includes a first conductive layer, a second conductive layer and an insulation layer which is interposed between the first and second conductive layers between the orientation film and the substrate, the insulation layer extends in the direction at least along an outer periphery of the display region, and includes a groove portion having a recessed groove which opens on the orientation film side, the first conductive layer is made of ITO and covers a surface of a liquid crystal layer side of the recessed groove, the first conductive layer on the groove portion having a recessed groove form along the recessed groove, the substrate which includes the groove portion includes a pixel electrode made of ITO in each pixel region, and the signal lines are formed in a state that the signal lines go around the recessed groove.
