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.

Claims (12)

1. A display device comprising:

a first substrate including a plurality of unit regions;

a unit electrode portion disposed on the first substrate and disposed in one unit region of the plurality of unit regions, the unit electrode having a substantially rectangular shape having four corners;

an opposed electrode facing the unit electrode portion; and

a liquid crystal layer including a plurality of liquid crystal molecules interposed between the unit electrode portion and the opposed electrode,

wherein the unit region comprises a plurality of subregions at which the liquid crystal molecules are tilted in different directions from each other when an electric field is generated in the liquid crystal layer,

the unit electrode portion includes a stem disposed between adjacent subregions of the unit region and continuously crossing through a center of the unit region, a plurality of branches extending from the stem, and at least one planar portion disposed in at least one corner of the unit electrode portion, and

the planar portion includes an oblique side extending in a direction perpendicular to an extending direction of the branches.

2. The display device of claim 1 , wherein the oblique side extends toward an oblique direction with respect to an extending direction of the stem, and the oblique side is disposed internally in the subregions.

3. The display device of claim 2 , wherein the oblique side is spaced apart from the branches facing the oblique side.

4. The display device of claim 1 , wherein a ratio of an occupied are of the planar portion in a corresponding subregion is equal to or less than about 50%.

5. The display device of claim 1 , wherein the planar portion has a substantially triangular shape.
