The invention provides a quantum dot film, a quantum dot light-emitting diode and a quantum dot color film substrate, which belong to the technical field of display. A quantum dot film provided by the present invention includes a plurality of quantum dots and a plurality of polymers. The polymer includes at least one first segment and at least one second segment. The tensile modulus of the first segment is greater than the tensile modulus of the second segment, and the flexural modulus of the second segment is smaller than the flexural modulus of the first segment. Since the polymer added in the quantum dot film has the first segment with high tensile modulus and the second segment with low flexural modulus, the second segment can make the quantum dot film have good bending properties. A chain segment can prevent the quantum dot film from expanding and decomposing under the influence of light and current, thereby improving the mechanical stability of the quantum dot film, avoiding cracks or irreversible deformation of the quantum dot film after repeated bending, and improving the Lifespan of quantum dot films. |
