Abstract: Embodiments of the present disclosure provide an array substrate and method for manufacturing same, a display panel, and a display device, and relate to the field of display technologies. The array substrate includes a color filter layer, such that a distance between a light source on a side, distal from the color filter layer, of the base substrate and the color filter layer is less. Thus, light from regions of the color resist blocks is avoided being emitted from adjacent color resist blocks, and a cross color of the display panel is further avoided, such that the display effect of the display panel is great. In addition, the color resist block is at least partially overlapped with a second portion of a metal oxide pattern in an oxide thin film transistor, such that an overall footprint of the oxide thin film transistor and the color filter layer can be reduced, so as to acquire the display panel of high PPI.
