Array substrate, display panel, and display device

A method for manufacturing an array substrate, comprising:

• depositing a first conductive structure layer on a substrate;
• patterning the first conductive structure layer to form a first conductive structure comprising a first connection portion provided with a first opening;
• depositing a preliminary interlayer insulation layer on the first conductive structure;
• patterning the preliminary interlayer insulation layer to form an interlayer insulation layer penetrated through by a via;
• depositing a second conductive structure layer on the interlayer insulation layer;
• patterning the second conductive structure layer to form a second conductive structure comprising a second connection portion,
• wherein the second connection portion is electrically coupled to the first connection portion through the via;
• an orthographic projection of the first opening on the substrate does not overlap an orthographic projection of the via on the substrate;
• and
• the first opening has at least one linear-shaped first sub-opening extending in a first direction parallel to the substrate and at least one linear-shaped second sub-opening extending in a second direction parallel to the substrate and intersecting the first direction.
