Abstract: The present application relates to a pixel structure, a method for manufacturing the same, a display panel and a display device. The pixel structure includes a plurality of sub-pixels, each of which has a triangular shape. Sub-pixels of four different colors constitute a pixel unit. Any two sub-pixels that have the same common triangle edge have different colors. Each row and each column of sub-pixels are composed of alternately arranged upright triangle sub-pixels and inverted triangle sub-pixels. Every adjacent six columns of sub-pixels constitute a group. Each row of sub-pixels includes sub-pixels of four different colors, and each group of sub-pixels has the same arrangement. The upright triangle sub-pixels are sub-pixels of the other three different colors, and all of the inverted triangular sub-pixels are sub-pixels of the first color.
