The present invention provides a liquid crystal display device providing uniform display without lowering the transmissivity. The present invention is a liquid crystal display device comprising: a first substrate and a second substrate positioned to face the first substrate; and a liquid crystal layer interposed between the first substrate and the second substrate, wherein the liquid crystal layer contains liquid crystal molecules having positive dielectric anisotropy, the liquid crystal molecule is aligned in a direction vertical to a surface of the first substrate when voltage is not applied, the first substrate comprises a pixel electrode and a common electrode, each comprising a core portion and a comb-tooth portion, the comb-tooth portions of the pixel electrode and of the common electrode are arranged in parallel with each other and alternately engaged at a constant interval, the core portion of the common electrode comprises two parallel portions that are in parallel with the longitudinal direction of the comb-tooth portion of the common electrode, the two parallel portions are each positioned outside the outermost comb-tooth portions of the pixel electrode, and (W−S)/(L+S) satisfies“2n+1”, in which“W”represents a distance between the two parallel portions,“L”represents the width of each of the comb-tooth portions of the pixel electrode and the common electrode,“S”represents a distance between a comb-tooth portion of the pixel electrode and an adjacent comb-tooth portion of the common electrode and also represents a distance between one of the outermost comb-tooth portions of the pixel electrode and one of the two parallel portions, and“n”represents the number of the comb-tooth portions of the common electrode.
