Embodiments of the present invention disclose a method for manufacturing an array substrate comprising: forming patterns of a thin film transistor structure and a passivation layer (7) on a base substrate (1) to define a plurality of pixel units on the base substrate; forming subsequently patterns of a transflective layer (8) and a color filter (9) in a pixel region (a) of the pixel unit, the color filter being disposed above the transflective layer; forming an organic light-emitting diode (11, 13, 14) in the pixel region of the pixel unit so that the transflective layer (8) and the color filter (9) are disposed between the organic light-emitting diode and the thin film transistor structure. Embodiments of the present invention also provide an array substrate.
