The application provides a quantum dot, a quantum dot photoresist, a display substrate and a display device. The quantum dots of the present application comprise an organic ligand from the group of compounds represented by X-a-Y, X comprising one of-SH, -COOH, -NH2, an organic phosphine oxide group, a comprising at least one of a polyol group, Y comprising at least one of a linear saturated or unsaturated aliphatic group, a branched saturated or unsaturated aliphatic group; the organic ligand of the quantum dot comprises an organic ligand X group with a surfactant effect, an A group with strong hydrophilicity and a Y group with increased solubility of an organic colloid. |
