Array substrate and method for manufacturing the same, display panel, and display device

A method for manufacturing an array substrate, comprising:

• providing a base substrate;
• forming a TFT array layer on the base substrate, wherein the TFT array layer comprises a plurality of driver transistors arranged in an array;
• forming a color resist layer on a side of the TFT array layer distal to the base substrate, wherein the color resist layer comprises a plurality of color resist patterns independent from each other, a first opening is formed between adjacent ones of the color resist patterns, and an orthogonal projection of the first opening onto the base substrate at least partially overlaps with an orthogonal projection of an output electrode in a respective one of the driver transistors onto the base substrate;
• forming pixel electrodes on a side of the color resist layer distal to the base substrate, wherein the pixel electrodes correspond to the driver transistors respectively, and the pixel electrode is connected to the output electrode in the corresponding driver transistor through the first opening;
• forming a planarization layer between the pixel electrodes and the color resist layer;
• and
• forming a common electrode layer between the planarization layer and the pixel electrodes, wherein the common electrode layer is provided with a second opening, and an orthogonal projection of the second opening onto the base substrate covers an entirety of the orthogonal projection of the first opening onto the base substrate.
