An array substrate and a method for manufacturing the same, a display panel and a touch panel are provided. The array substrate includes multiple pixel regions arranged in an array. Multiple metal patterns are provided within each pixel region. Each metal pattern includes multiple metal units which are periodically arranged. The multiple metal patterns are capable of reflectively filtering light from ambient environment or from a front light source. Each pixel region includes multiple sub-pixel regions which are in a one-to-one correspondence with the multiple metal patterns within the pixel region. Metal units of metal patterns corresponding to sub-pixel regions of different colors have different arrangement periods.
