Furthermore, by maximizing the distance between the storage capacitor electrode 1 and the signal line 2 within the limited space of the circuit design, the parasitic capacitance generation region 8 is moved as far away from the signal line 2 as possible, thereby reducing the coupling interference of the enable signal to the data signal through the parasitic capacitance.

[0049] Furthermore, in some embodiments of this disclosure, the dimension of the second portion 6 along the extension direction is larger than the dimension of the storage capacitor electrode along the extension direction.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model.
