Description
technical field [0001] The invention relates to the field of display technology, in particular to a thin film transistor array substrate and a display panel using the thin film transistor array substrate. Background technique [0002] The display panel includes a thin film transistor array substrate, an opposite substrate, and a liquid crystal layer located between the thin film transistor array substrate and the opposite substrate. A common electrode and a pixel electrode are arranged on the thin film transistor array substrate. The voltage difference between the common electrode and the pixel electrode is used to drive the liquid crystal in the liquid crystal layer to rotate. [0003] During the working process of the display panel, the voltages on the common electrode need to be kept consistent. However, the existing common electrodes have a large area, and due to factors such as different loads, there are deviations in the voltages at different positions of the common ...
