Document Type and Number:
WIPO Patent Application WO/2023/283976
Kind Code:
A1
Abstract:
Provided are a display panel (100) and a display device. The display panel (100) comprises pixel electrodes (11) and common electrodes (21) opposite to each other, and light-shielding electrodes (12) located in gaps of the pixel electrodes (11). A hole is formed on the common electrode (21) corresponding to the light-shielding electrode (12), and preset voltage on the light-shielding electrode (12) is adjusted, such that a vertical electric field is formed between the common electrode (21) and the corresponding light-shielding electrode (12), thereby hindering the lateral movement of impurity ions to alleviate the problem of line residues in the existing LCD panel.
