1. A liquid crystal display device comprising:

  • a first substrate;

    a second substrate;

    a liquid crystal layer sandwiched between the first substrate and the second substrate, anda display portion formed on the first substrate,the display portion including;

    a plurality of data lines extending in a first direction;

    a plurality of gate lines extending in a second direction which is different from the first direction; and

    a plurality of pixel regions formed in a matrix, each of the pixel regions being surrounded by the data lines and the gate lines, wherein;

    each of the plurality of pixel regions includes;

    a thin film transistor connected to the data line;

    a pixel electrode connected to the thin film transistor; and

    a common electrode that is opposed to the pixel electrode,the plurality of pixel regions in the display portion are divided into a plurality of areas, each of the plurality of areas including at least two pixel regions arranged adjacent to each other,the plurality of areas include a plurality of first areas and a plurality of second areas,in each of the plurality of pixel regions in each of the first areas, one of (i) the pixel electrode and (ii) the common electrode is formed closer to the liquid crystal layer than the other of (i) the pixel electrode and (ii) the common electrode,in each of the plurality of pixel regions in each of the second areas, the other of (i) the pixel electrode and (ii) the common electrode is formed closer to the liquid crystal layer than the one of (i) the pixel electrode and (ii) the common electrode,in each of the plurality of pixel regions in each of the first areas, the pixel electrode is formed in only a first layer, and the common electrode is formed in only a second layer, the first layer being a different layer than the second layer, andin each of the plurality of pixel regions in each of the second areas, the pixel electrode is formed in only the second layer, and the common electrode is formed in only the first layer.
