A liquid crystal display device includes: first and second substrates; a liquid crystal layer interposed between the first and second substrates; a switching element provided on the first substrate; a first pixel electrode provided on the first substrate and electrically connected to a drain electrode of the switching element; an insulating film provided on the first pixel electrode; and a common electrode provided on the insulating film and including a first slit. The first pixel electrode extends in a first direction. The first slit extends in the first direction and is located above the first pixel electrode. In a planar view, both edges of the first pixel electrode in a second direction intersecting the first direction are located inside the first slit.
