Display substrate and display device

A display substrate, comprising:

• a base substrate;
• and
• a sub-pixel, comprising a pixel circuit, the pixel circuit comprising a light emitting device, a driving transistor and a storage capacitor,
• wherein the driving transistor comprises an active pattern and a gate electrode, the active pattern of the driving transistor comprises a channel region, a planar shape of the channel region of the driving transistor extends along a second direction as a whole;
• the display substrate further comprises a first electrode plate and a second electrode plate, the first electrode plate is in a same layer as the gate electrode of the driving transistor, and at least a portion of the second electrode plate and the first electrode plate form the storage capacitor;
• the first electrode plate comprises a first portion and a second portion, the first portion of the first electrode plate has a first terminal in the second direction, and the first terminal of the first electrode plate and the second portion of the first electrode plate form a blank notch.
