1. A liquid crystal display device comprising:

  • a TFT substrate on which a pixel is formed in each of regions surrounded by scanning lines which extend in the first direction and are arranged parallel to each other in the second direction and video signal lines which extend in the second direction and are arranged parallel to each other in the first direction;

    a counter substrate which is arranged to face the TFT substrate in an opposed manner; and

    a liquid crystal layer which is sandwiched between the TFT substrate and the counter substrate, whereina pixel electrode formed in a planar shape and a counter electrode formed in a comb-teeth shape on the pixel electrode by way of an insulation film are arranged in the pixel,columnar spacers which define a distance between the TFT substrate and the counter substrate are formed over the counter substrate,a bus electrode made of metal which extends in the first direction and is connected with the counter electrode is formed over the scanning line formed over the TFT substrate, anda distal end of the columnar spacer faces the bus electrode in an opposed manner, and a width of the bus electrode is 3 μ

    m or less.
