Abstract
A display substrate (20) and a display device (40). The display substrate (20) comprises a base substrate and a plurality of sub-pixels (100) located on the base substrate. Each sub-pixel (100) comprises a pixel circuit and a pixel electrode (134) electrically connected to the pixel circuit, and each pixel circuit comprises a driving sub-circuit. The pixel electrodes (134) each comprises an electrode body part (140) and a first electrode extension part (142) extending from the electrode body part (140). The display substrate (20) comprises first-type sub-pixels. The electrode body part (140) of each first-type sub-pixel (100) does not overlap a control electrode of the driving sub-circuit of the sub-pixel or an electrode part directly electrically connected to the control electrode, and the first electrode extension part (142) of each pixel electrode (134) at least partially overlaps the control electrode or the electrode part. The first-type sub-pixels comprises at least two sub-pixels (100) configured to emit light of different colors. The display substrate (20) can effectively improve display quality.
