The column storage capacitor electrodes, for example, the storage capacitor electrodes 91, 92, 93, are disposed in parallel on the first substrate ^90. The two ends of the storage capacitor electrodes are connected to an annular metal line 95 ′ and are electrically connected to the constant voltage source (not shown in FIG. 1 ) through the plurality of wires 97 via the annular metal line 95 . This constant voltage source is used to provide a common voltage to each column of storage capacitor electrodes. Among them, a single column storage capacitor electrode is substantially a plurality of elements. Since the storage capacitor electrodes 91, 92, 93, the annular metal wires 95, and the wires 97 have substantially electric resistance, the longer the current transfer path between the constant voltage source and the pixel, the higher the resistance value of the current transmission path. Taking the picture element ^ and the pixel Q0 as an example, the current transmission path between the pixel P0 and the constant voltage source is longer than the current path between the element Q0 and the constant voltage source, so the pixel P0 current transmission path is The resistance value is high. As a result, the values of the common voltage received by the pixel P0 and the pixel Q0 are inconsistent, so that the liquid crystal display device displays an incorrect picture, and the brightness uniformity of the liquid crystal display device decreases.

The second substrate is configured relative to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate. Wherein at least a portion of the dry storage capacitor electrode of each column of storage capacitor electrodes is electrically connected to another column of storage capacitor electrodes. According to another aspect of the present invention, a liquid crystal display device includes a liquid crystal display panel and a backlight module. The liquid crystal display panel includes a first substrate, a second substrate and a liquid crystal layer.
