Active component array base board 200d comprises a substrate 210, multi-strip scanning line 220a ', many data wire 220b ' and a plurality of pixel cell 230c.Wherein, multi-strip scanning line 220a ', many data wire 220b ' and a plurality of pixel cell 230c all are disposed on the substrate 210.Each pixel cell 230c comprises an active member 232b, a pixel electrode 234c and a plurality of auxiliary electrode 238.Active member 232b electrically connects scan line 220a ' and data wire 220b ', and active member 232b for example is amorphous silicon membrane transistor or polycrystalline SiTFT.
In same pixel cell 230c, pixel electrode 234c electrically connects active member 232b, and has a plurality of by the open S of pixel electrode 234c edge toward the inner extension of pixel electrode 234c '.These auxiliary electrodes 238 of part electrically connect with the pixel electrode 234c that back one-level scan line 220a ' is controlled, and these auxiliary electrodes 238 of other parts electrically connect with the pixel electrode 234c that previous stage scan line 220a ' is controlled.Each auxiliary electrode 238 comprises that one is configured in these open S ' one of them interior extension A '.In addition, these pixel electrodes 234c and these auxiliary electrodes 238 can be to adopt transparent conductive material made, for example indium tin oxide or indium-zinc oxide.
