US 12,663,681 B2 · Display panel and method of fabricating the same

Abstract

A display panel includes a substrate, multiple scan lines, multiple data lines, and multiple pixel structures. The scan lines and the data lines are disposed on the substrate. The pixel structure is disposed on the substrate and electrically connected to the scan lines and the data lines, and includes an active device, a pixel electrode, a capacitor electrode, an overcoat layer, a first common electrode, a second common electrode, a first passivation layer, and a second passivation layer. The active device is electrically connected one scan line, one data line, and the pixel electrode. The capacitor electrode extends from a drain and is electrically connected to the pixel electrode. The overcoat layer is disposed between the pixel electrode and the capacitor electrode. The first common electrode overlaps the capacitor electrode, and is located between the overcoat layer and the capacitor electrode. The second common electrode overlaps the pixel electrode, and is located between the overcoat layer and the pixel electrode. The first passivation layer is disposed between the capacitor electrode and the first common electrode. The second passivation layer is disposed between the second common electrode and the pixel electrode.
