Abstract: A substrate is provided, which includes a base, a light shielding metal layer, a signal line layer, and a pixel electrode layer. The light shielding metal layer is located on the base and includes patterned shield electrodes. The signal line layer includes patterned data lines. The pixel electrode layer includes patterned pixel electrodes. Furthermore, a superposition region is present on an orthogonal projection of the data lines on the base and an orthogonal projection of the shield electrodes on the base.

Abstract: An array substrate and a display panel are provided. The array substrate includes scanning lines, data lines, pixel electrodes disposed between the scanning lines and the data lines, and thin film transistors electrically connected to the scanning lines, data lines, and pixel electrodes. By disposing openings on positions of gate electrodes of the thin film transistors corresponding to drain electrodes, a problem of inconsistent parasitic capacitance between the gate electrodes and the drain electrodes of the thin film transistors due to position shifting of the drain electrodes of the thin film transistors can be solved, thereby improving display quality of the display panel using the array substrate.
