Thin film transistor array substrate and LCD

Abstract

The invention provides a thin film transistor array substrate and an LCD. A plurality of scan lines and a plurality of data lines orthogonally define a first sub-pixel area, a second sub-pixel area and a third pixel area. A patterned conducting layer is formed on the substrate, and comprises a first conducting part, a second conducting part and a third conducting part which are respectively located in the first sub-pixel area, the second sub-pixel area and the third sub-pixel area; a plurality of capacitor electrodes comprise a first capacitor electrode, a second capacitor electrode and a third capacitor electrode which are respectively located above the first conducting part, the second conducting part and the third conducting part; the capacitor electrodes and the patterned conducting layer are coupled as a plurality of pixel storage capacitors; and a spacer is arranged above the third capacitor electrode, wherein, the shape of the third capacitor electrode is different from the shape of the first capacitor electrode and the shape of the second capacitor electrode, and the maximum width of the third capacitor electrode in the extension direction of the pattered conducting layer is larger than that of the first capacitor electrode and the second capacitor electrode in the extension direction of the pattered conducting layer.

Description

technical field [0001] The invention relates to a liquid crystal display device and a thin film transistor array substrate thereof, and in particular to a liquid crystal display device and a thin film transistor array substrate capable of preventing flickering. Background technique [0002] figure 1 A schematic circuit diagram of a general thin film transistor liquid crystal display device is shown. Please refer to figure 1 , the sub-pixels SP located on the same column of the general liquid crystal display device 10A 、SP 10B 、SP 10C Thin Film Transistor TFT of ... 10A 、TFT 10B 、TFT 10C ...are all driven by the same scan line (scan line) S10, usually a main pixel is composed of three sub-pixels, for example, a main pixel that can display any desired color is usually composed of three sub-pixels of red, green and blue composition. When the scan line S10 provides a sufficient turn-on voltage, the thin film transistor TFT connected to the scan line S10 10A 、TFT 10B 、...

In this way, the sub-pixel SP 20A 、SP 20B with SP 20C Although you can get a C ST-A =C ST-B =C ST-C results in maintaining the feedthrough voltage V FD-A ≈V FD-B ≈V FD-C However, the aperture ratio of the remaining sub-pixels will be sacrificed and the overall display brightness will be reduced, which will greatly affect the display quality and product performance.
