Abstract

An array substrate includes multiple gate lines, multiple data lines, and multiple light-shielding electrode lines. The multiple gate lines and the multiple data lines intersect each other to circumferentially delimit a plurality of sub pixels. The multiple light-shielding electrode lines are arranged to correspond to the multiple data lines. The plurality of sub pixels includes a blue sub pixel column corresponding to a blue color filter. At least one sub pixel of the blue sub pixel column includes a light-shielding electrode. The light-shielding electrode is connected to light-shielding electrode lines that are located on two opposite sides of the blue sub pixel column. Displaying abnormality that occurs in displaying pure blue or pure yellow images can be avoided. Also provided is a display panel.
