Abstract:
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 a first direction and are arranged parallel to each other in a 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, wherein a pixel electrode made of a transparent conductive film formed in a planar shape, and a counter electrode made of a transparent conductive film and 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 gate insulation film is formed on the scanning lines, the video signal lines are formed over the gate insulation film, a passivation film is formed on the video signal lines, and the insulation film is formed over the passivation film, a bus electrode made of elemental metal which extends in the first direction and is connected with the counter electrode is formed over the insulation film and the scanning line formed over the TFT substrate, an alignment film formed over the counter electrode, the insulation film, and the bus electrode, and a distal end of the columnar spacer faces the bus electrode in an opposed manner, and the bus electrode which extends in the first direction has a width which is no greater than 3 μm and which is less than a width of the scanning line which extends in the first direction.
