Color conversion film, display panel using color conversion film and method for manufacturing color conversion film

A method of manufacturing a color conversion film, the color conversion film comprising:

• a plurality of first sub-pixels emitting a first primary color light, a plurality of second sub-pixels emitting a second primary color light, and a plurality of third sub-pixels emitting a third primary color light,
• the method comprising:
• providing a substrate comprising a first surface and a second surface, the first surface being an outer topmost surface of the substrate, and the second surface being an outer lowest surface of the substrate;
• forming a plurality of first indentations on the first surface and forming a plurality of second indentations on the second surface, wherein each of the plurality of first indentations does not extend through the second surface, a first distance is defined between a bottom of each of the plurality of first indentations and the second surface, each of the plurality of second indentations does not extend through the first surface, and a second distance is defined between a bottom of each of the plurality of second indentations and the first surface;
• forming a plurality of first quantum dot blocks in the first indentations to convert an incident light to a first primary color light and curing the first quantum dot blocks in the first indentations;
• forming a first passivation layer on the first surface to seal the first quantum dot blocks in the first indentations;
• forming a plurality of second quantum dot blocks in the second indentations to convert an incident light to a second primary color light and curing the second quantum dot blocks in the second indentations;
• and
• forming a second passivation layer on the second surface to seal the second quantum dot blocks in the second indentations.
