An array substrate includes a base substrate, a conductive layer on a side of the base substrate, a light adjustment layer on a side of the conductive layer away from the base substrate, a plurality of signal lines on a side of the base substrate away from the conductive layer, and a protective layer between the light adjustment layer and the base substrate. The conductive layer includes a plurality of pads electrically connected with electronic elements. An orthographic projection of at least part of the light adjustment layer on the base substrate does not overlap an orthographic projection of the conductive layer on the base substrate, and is located in gaps between orthographic projections of adjacent signal lines on the base substrate. An orthographic projection of the protective layer on the base substrate at least covers the orthographic projection of the at least part on the base substrate.
