Abstract

An array substrate and a manufacturing method therefor, an organic light emitting diode display device and a display substrate are provided. The array substrate includes: a base substrate and a first color sub-pixel and a second color sub-pixel on the base substrate. The first color sub-pixel includes a first driving transistor, the second color sub-pixel includes a second driving transistor, and a channel width-length ratio of the first driving transistor is greater than a channel width-length ratio of the second driving transistor.
