Thin film transistor base plate 20 also comprises at least one first sweep trace S1, one second sweep trace S2, one first data line D1, one second data line D2 and a contact hole 215A.The first sweep trace S1, the second sweep trace S2, the first data line D1 and the second data line D2 are arranged on the ground 200, define a pixel P.Thin film transistor (TFT) T and pixel electrode 210 are arranged in pixel P, and thin film transistor (TFT) T couples with pixel electrode 210, the first data line D1 and the first sweep trace S1 respectively.Contact hole 215A is arranged on the ground 200 corresponding to the first contact hole couplings 215.
Wherein, vertically trunk electrode 212 is parallel to the first data line D1, and a dried electrode 214 is arranged in parallel in each zone, and non-perpendicularly is connected in vertical trunk electrode 212.Because vertically trunk electrode 212 defines four zones with the horizontal trunk electrode 213 vertical cross structures that connect into, simultaneously the dried electrode 214 in the adjacent area is vertical mutually, therefore make dried electrode 214 in four zones, vertically trunk electrode 212 and laterally trunk electrode 213 constitute a M shape structure.Preferably, all dried electrodes 214 for example are 45 degree with respect to vertical trunk electrode 212 or horizontal trunk electrode 213 inclinations one angle.The first contact hole couplings 215 is adjacent to the first data line D1 or the first sweep trace S1, and is arranged at the end of vertical trunk electrode 212.Preferable, the end of vertical trunk electrode 212 is connected with a corner of the first contact hole couplings 215, make the first contact hole couplings 215 be positioned at the lower left of vertical trunk electrode 212 ends.

11Pairing position is the first contact hole couplings, 215, the second dark line district A
12Pairing position is the second contact hole couplings 216.Because vertically an end of trunk electrode 212 is offset left, extends on the first contact hole couplings 215, and the dark line phenomenon on vertical trunk electrode 212 is transferred on the first contact hole couplings 215.And owing to cooperate the design of non-sealing opening 218, make between these the dried electrodes 214 and the first contact hole couplings 215 not connect, avoid producing the sealing opening.After applying voltage, the false edges electric field energy of this non-sealing opening 218 and the first contact hole couplings 215 separates with the correct fringe field that non-sealing opening 218 and these dried electrodes 214 are partly produced clearly.Therefore, can be with the distribution limitation of dark line in vertical trunk electrode 212, laterally on trunk electrode 213, these dried electrodes 214, the first contact hole couplings 215 and the second contact hole couplings 216, and then the first contact hole couplings, 215 pairing dark lines and vertical trunk electrode 212 pairing dark lines are separated.Thus, can reduce the continuous distribution scope of dark line, to increase the penetrance of display panels.
In addition, because the first contact hole couplings 215 is in order to coupling with thin film transistor (TFT) T, the first contact hole couplings 215 itself is light tight.Therefore, dark line phenomenon does not herein influence penetrance.In design, also can directly the first contact hole couplings 215 be designed on vertical trunk electrode 212, make the first dark line district A
11Overlapping with the dark line phenomenon on vertical trunk electrode 212, with further lifting penetrance.
The dark line that please contrasts Figure 1B and Fig. 2 B simultaneously distributes, and the design of the pixel electrode 210 of the embodiment of the invention one has reduced the distribution of dark line effectively.The first dark line district A in Figure 1B
