Array substrate and display device having the same
View Patent ↗An array substrate includes a lower substrate, a switching element and a pixel electrode. In the lower substrate, unit pixel areas are each divided into a plurality of domains. The switching element is disposed on the lower substrate and transmits a pixel signal. The pixel electrode is disposed on the unit pixel area and is electrically connected to the switching element. The pixel electrode includes a plurality of slit portions disposed thereon. A portion of the slit portions is longitudinally extended in a zigzag shape along different directions in correspondence with the domains.
1. An array substrate comprising:
a lower substrate including unit pixel areas each divided into a plurality of domains;
a switching element disposed on the lower substrate and which transmits a pixel signal; and
a pixel electrode connected to the switching element, the pixel electrode including a plurality of a slit portions, at least one of the slit portions having a plurality of bents bent in different directions with different angles to the data line as the at least one of the slit portions extends only away from the data line in a unit pixel area.
2. The array substrate of claim 1 , wherein the pixel electrode further comprises a support electrode part longitudinally extended along a boundary between adjacent domains of the unit pixel area, and disposed continuous with the slit portions, and
the slit portions are symmetrically arranged with respect to the support electrode part.
3. The array substrate of claim 2 , wherein the pixel electrode further comprises a first pixel electrode and a second pixel electrode disposed in a main pixel area of the unit pixel area and a sub-pixel area of the unit pixel area, respectively, and
each of the first and second pixel electrodes comprises the support electrode part and the slit portions.
4. The array substrate of claim 3 , wherein the slit portion comprises:
a zigzag portion directly extended from the support electrode part in a center portion of the main pixel area and a center portion of the sub-pixel area in the zigzag shape; and
a straight line portion extended directly from the zigzag portion to an outer portion of the unit pixel area in a straight line shape, the zigzag portion and the straight line portion disposed continuous with each other.
5. The array substrate of claim 3 , wherein the slit portion comprises:
a straight line portion directly extended from the support electrode part in a center portion of the main pixel area and a center portion of the sub-pixel area in a straight line shape; and
a zigzag portion directly extended from the straight line portion to an outer portion of the unit pixel area in the zigzag shape, the straight line portion and the zigzag portion disposed continuous with each other.
6. The array substrate of claim 3 , wherein an entire of the slit portion is directly extended from the support electrode part to an outer portion of the unit pixel area in the zigzag shape.
