Liquid crystal display device

A liquid crystal display device comprising:

• a pair of substrates;
• and
• a liquid crystal layer interposed between the pair of substrates, at least one of the pair of substrates comprising a first electrode that includes at least two parallel comb teeth and at least two parallel slits, a second plate electrode, and an insulating film that separates the first electrode and the second electrode into different layers,
• assuming that the width of a comb tooth is L1 and the width of another comb tooth is L2 among the at least two comb teeth;
• and that the width of a slit is S1 and the width of another slit is S2 among the at least two slits, then L1, L2, S1, and S2 satisfy the following formulas (H1) to (H6):
• S1/L2<W (H1)
• Z<S2/L1 (H2)
• 1.27<W<1.60 (H3)
• 1.27<Z<1.60 (H4)
• S1≦S2 (H5)
• L1≦L2 (H6)
• provided that S1 and L1 are not simultaneously equal to S2 and L2, respectively;
• when the at least two slits include three or more slits having different widths, S1 is set as the minimum width, and S2 is set as the maximum width;
• and when the at least two comb teeth include three or more comb teeth having different widths, L1 is set as the minimum width, and L2 is set as the maximum width.
