Description

technical field [0001] The present invention relates to a pixel structure of a display device, and in particular to a pixel structure in which a first metal plate and a second metal plate are coupled to form a storage capacitor. Background technique [0002] FIG. 1A shows a partial schematic diagram of a pixel structure in a conventional display panel. Wherein, the pixel 100 is controlled by the scan line SC1 and receives the data signal transmitted by the data line DT1. FIG. 1B shows a cross-sectional structure diagram of the pixel 100 , wherein the cross-sectional structure diagram is a cross-section along the directions A1 , B1 to C1 in FIG. 1A . [0003] As shown in FIG. 1B , the pixel structure of the pixel 100 is formed by an indium tin oxide layer (ITO), a passivation layer, two metal plates, an interlayer dielectric (ILD), an oxide layer, and a polysilicon layer. The pixel 100 includes a transistor 110 and storage capacitors Cp1 and Cp2. The gate of the transistor...

Problems solved by technology

[0005] However, due to process problems, metal particles (particles) remain between the metal plates 130a and 140, and the metal plates 130a and 140 are accidentally shorted.

Therefore, the storage capacitor Cp1 located between the metal plates 130a and 140 will disappear, resulting in a bright spot in the pixel 100
