Abstract

An array substrate includes: a first substrate (10), including a plurality of sub-pixel regions (101) arranged in an array along a row direction (X) and a column direction (Y); a pixel circuit layer, including a plurality of sub-pixel circuits; a planarization layer (17), provided with a first via hole (170) located in the sub-pixel regions (101), and includes at least one pattern portion (171), the pattern portion (171) includes a plurality of pattern units (171a) arranged in an array along the row direction (X) and the column direction (Y); and a reflective electrode layer, wherein the reflective electrode layer includes a plurality of reflective electrodes (18) that are mutually disconnected, each of the reflective electrodes (18) is located in one of the sub-pixel regions (101) and is electrically connected to the sub-pixel circuit through the first via hole (170).
