Abstract

A liquid crystal display device includes a first substrate; a first pixel electrode disposed on the first substrate and including a first body portion, a first sub-edge portion on a first side of the first body portion, and a second sub-edge portion, which on a second side of the first body portion; and a shield electrode on the same layer as the first pixel electrode a shield electrode on the same layer as the first pixel electrode and extending from a first side of the first sub-edge portion in a first direction. The first body portion includes a first stem portion, a second stem portion that intersects the first stem portion, and a plurality of branch portions extending from at least one of the first stem portion and the second stem portion. The first sub-edge portion is spaced apart from the branch portions and has a bent portion.
