摘要： An array substrate and a liquid crystal display panel are provided. A shielding electrode is at least arranged between a data line and a pixel electrode. On a base substrate, an orthogonal projection of the shielding electrode and an orthogonal projection of the data line both overlap with an orthogonal projection of a portion of a trunk electrode extending along a direction of a data line, so that the shielding electrode shields a coupling effect between the data line and the pixel electrode. By arranging the data line and the shielding electrode in an area corresponding to the trunk electrode of a pixel electrode, less space or no space are occupied by the shielding electrode and the data line. The present application increases an aperture ratio of the pixel and increases a transmittance of the display panel.
