Abstract
An array substrate, a method for manufacturing an array substrate, a liquid crystal cell and a display apparatus are provided. The array substrate includes: a first base substrate; thin film transistors; a first planarization layer; a common electrode on a side of the first planarization layer away from the thin film transistors; a first dielectric layer on a side of the common electrode away from the first planarization layer; first pixel electrodes on a side of the first dielectric layer away from the common electrode; the first pixel electrodes are electrically connected to the thin film transistors in a one-to-one correspondence through first vias extending through the first dielectric layer and the first planarization layer; a surface of each first pixel electrode away from the first base substrate is provided with a first groove at least corresponding to a corresponding first via.
