Abstract:
1. A liquid display device, comprising: a liquid crystal layer sandwiched between a pair of insulation substrates disposed facing each other; a plurality of gate lines formed on one of the insulation substrates; a plurality of source lines formed crossing, over an intervening first insulation film, the plurality of gate lines; switching elements formed on crossings between the plurality of gate lines and the plurality of source lines; pixel electrodes connected to the switching elements; common electrodes formed facing the pixel electrodes, for generating between the pixel electrodes and the common electrodes an electric field directed approximately parallel to the insulation substrates; first shielding electrode patterns formed along the source lines in a layer, with the first insulation film intervening, underneath the source lines, at least partially overlapping the source lines widthwise; and plural second shielding electrode patterns formed along the source lines, overlapping the first shielding electrode patterns and without substantially overlapping the source lines in a layer, with a second insulation film intervening, above the source lines, the first shielding electrode patterns having a same electric potential as the second shielding electrode patterns, wherein the second shielding electrode patterns are wider than the common electrodes.
