Abstract: An exemplary embodiment of the present disclosure provides a display device including a first substrate including a plurality of unit regions, a unit electrode portion disposed on the first substrate in one unit region, an opposed electrode facing the unit electrode portion, a liquid crystal layer interposed between the unit electrode portion and the opposed electrode, and a protrusion interposed between the first substrate and the liquid crystal layer and protruded toward the liquid crystal layer. The protrusion includes a pair of horizontal portions facing each other and including a side parallel to a first direction, a pair of vertical portions facing each other and including a side parallel to a second direction different from the first direction, and at least one corner portion including a first oblique side parallel to a direction oblique with respect to the first and second directions.
