A liquid-crystal display device includes: a substrate; and an insulation film disposed on the substrate and which includes a flat portion and a projection pattern unit protruding from the flat portion in a direction perpendicular to the flat portion; and a pixel electrode disposed on the substrate. The pixel electrode includes a first stem electrode and a second stem electrode extending along a first direction and disposed to be spaced apart from the first stem in a second direction perpendicular to the first direction, and a plurality of branch electrode extending from the first stem electrode and the second stem electrode, and the projection pattern unit includes a first projection pattern extending along the first direction and partially overlapping the first stem electrode, and a second projection pattern extending along the first direction and partially overlapping the second stem electrode.
