In a liquid crystal display device having a first planar electrode and a second electrode formed on the first electrode with an insulating film in between, the response time of a liquid crystal is made shorter than that in a related art. A liquid crystal display device includes: a first substrate having a first electrode, an insulating film provided in an upper layer than the first electrode, and a second electrode provided in an upper layer than the insulating film; a second substrate; and a liquid crystal sandwiched between the first substrate and the second substrate. The liquid crystal display device drives the liquid crystal by generating an electric field by the first electrode and the second electrode. The second electrode has plural slits closed at both ends, the first electrode is a planar electrode superimposed on the plural slits, and, given that the length of the respective slits is Ls, the length Ls of the respective slits satisfies 12 μm≦̸Ls≦̸30 μm, more preferably, 12μm≦̸Ls≦̸20 μm.
