         10 . The display device as claimed in  claim 9 , wherein in the first direction, a width of at least one of the first extending portion adjacent to the first main portion is greater than a width of at least one of the first extending portion away from the first main portion. 
     
     
         11 . A display panel, comprising:
 a first substrate;   a second substrate;   a liquid-crystal layer, disposed between the first substrate and the second substrate;   a data line, disposed on the first substrate;   a first electrode, disposed on the first substrate,   wherein the first electrode comprises a first main portion, a first peripheral portion and a plurality of first extending portions connected to the first main portion and the first peripheral portion;   wherein at least a portion of the first peripheral portion is parallel to the data line and comprises at least one first curved side.   
     
     
         12 . The display panel as claimed in  claim 11 , wherein the first main portion is cross-shaped. 
     
     
         13 . The display panel as claimed in  claim 11 , further comprising a scan line, disposed on the first substrate, wherein an extending direction of the scan line differs from an extending direction of the data line, and another portion of the first peripheral portion is parallel to the scan line. 
     
     
         14 . The display panel as claimed in  claim 11 , further comprising a second electrode, wherein the second electrode is separated from the first electrode, and the second electrode comprises a second main portion and a plurality of second extending portions.
