In dot structure 132A, active member TFT can comprise grid G, channel layer CH, source S and drain D, and it can be understood as thin film transistor (TFT) as known in the art.Simultaneously known with reference to Fig. 2 and Fig. 4, grid G is connected to sweep trace SL, or in other embodiments, grid G can be defined by a part of sweep trace SL and form.Channel layer CH is overlapped in grid G, is namely positioned at grid G side in a thickness direction.Source S is connected to data line DL.Drain D is connected to the first pixel electrode E1 in the present embodiment.In addition, insulation course I1 is arranged between grid G and channel layer CH, and insulation course I2 covers active member TFT.First pixel electrode E1 is positioned at the side of insulation course I2 away from first substrate 110, and insulation course I1 and insulation course I2 all covers the second pixel electrode E2 to be separated by the first pixel electrode E1 and the second pixel electrode E2.Active member TFT has bottom gate type design in the present embodiment, that is grid G is positioned at the bottom of channel layer CH close to first substrate 110, but active member TFT also can have top gate type design or the structure of other thin film transistor (TFT)s.
In the present embodiment, the first pixel electrode E1 is connected to active member TFT.So when showing, the first pixel electrode E1 can receive the pixel potential that data line DL transmits, and the second pixel electrode E2 then can be transfused to common potential.Thus, dot structure 132A can provide the first driving electric field F1 and second to drive electric field F2 to liquid crystal layer 150.First drives electric field F1 and second to drive the given current potential of electric field F2 each freedom to define, suitable clear and definite of both difference.So liquid crystal layer 150 can have desirable liquid crystal efficiency.Also therefore, display panels 100A, as described above, relative Known designs can improve the problem of colour cast with great visual angle more significantly.
