Sustrate comprising quantum rod film and method for manufacturing the same, display panel

A substrate comprising a quantum rod film, wherein the substrate is manufactured according to a following method:

• S10:
• forming a first film on a first base;
• S20:
• treating the first film formed in S10 to form a plurality of first areas which are arranged with gaps therebetween and are strip-shape structures with micrometer-scale widths, wherein other areas on the first film are second areas, and the first areas and the second areas have opposite hydrophilicity and hydrophobicity;
• S30:
• coating a solution comprising quantum rod assemblies onto the first film obtained in S20 to form a quantum rod sub-film, the quantum rod assemblies having same hydrophilicity and hydrophobicity as the first areas, having micrometer-scale sizes, and being arranged sequentially in the first areas;
• S40:
• coating an adhesive on the quantum rod sub-film and attaching a second base to the adhesive;
• S50:
• peeling off the first base and transferring a first quantum rod sub-film onto the second base;
• and
• S60:
• repeating S10 to S40 at least once on the first quantum rod sub-film to form at least two quantum rod sub-films on the second base;
• wherein, the quantum rod film comprises all the quantum rod sub-films, orthographic projections of the first areas for making different quantum rod sub-films on the second base do not overlap, and all the orthographic projections of the first areas on the second base cover a surface of the second base entirely.

A display panel, which comprises:

• a first substrate,
• a second substrate opposite the first substrate, and
• a liquid crystal layer arranged between the first substrate and the second substrate;
• wherein the first substrate is a substrate comprising a quantum rod film, and a polarizing layer is arranged at a side of the second substrate far away from the liquid crystal layer;
• and
• the first substrate is manufactured according to a following method:
• S10:
• forming a first film on a first base;
• S20:
• treating the first film obtained in S10 to form a plurality of first areas which are arranged with gaps therebetween and are strip-shape structures with micrometer-scale widths, wherein other areas on the first film are second areas, and the first areas and the second areas have opposite hydrophilicity and hydrophobicity;
