Problems solved by technology

Please refer to image 3 , it is worth noting that during the manufacturing process, when the dielectric layer 126 is broken due to particles P falling on the dielectric layer 126 in the storage capacitor 120 or other factors, the storage capacitor 120 will have capacitance leakage (leakage) The phenomenon that the pixel structure 100 cannot be effectively charged (when the thin film transistor 110 is turned on), and abnormal leakage will occur (when the thin film transistor 110 is turned off), which in turn causes poor display quality of the liquid crystal display

[0043] Figure 4 The drawing is a schematic diagram of the pixel structure of the first embodiment of the present invention. Please refer to Figure 4 The thin film transistor array substrate of this embodiment has a plurality of pixel structures 200 arranged in an array, scanning lines 240 and data lines 250. The pixel structure 200 includes a switching element 210, a storage capacitor 220, and a pixel electrode 230. In view of the above, the switching element 210 is electrically connected to the storage capacitor 220 and the pixel electrode 230, and Figure 4 It can be clearly seen that the switch element 210 is electrically connected to the storage capacitor 220 and the pixel electrode 230 through the contact window 10. However, those skilled in the art can electrically connect the switching element 210 with the storage capacitor 220 and the pixel electrode 230 in other ways.

[0053] Figure 7 Shown is a schematic diagram of the storage capacitor according to the second embodiment of the present invention. Please refer to Figure 7 This embodiment is very similar to the first embodiment, and the main difference is that: in the storage capacitor 320 of this embodiment, the first capacitive coupling portion 322a and the first connecting portion 322b, and the second capacitive coupling portion 324a and the second The connection parts 324b are different in number, design shape, and connection mode, but they also have the effect of avoiding complete failure of the storage capacitor 220 from the first embodiment. Specifically, this embodiment adopts the design of 8 or more first capacitive coupling portions 322a, and each first capacitive coupling portion 322a is connected to other first capacitive coupling portions 322b and 322b' through more than two first connecting portions 322b and 322b'. A capacitive coupling portion 322a.
