Abstract
The present invention provides a color filter film manufacturing method and a color filer film. The color filter film manufacturing method of the present invention includes forming transparent photoresist layers in blue sub-pixel zones and forming first and second recesses respectively in red and green sub-pixel zones and subjecting bottoms thereof to a treatment for hydrophilicity/hydrophobicity. The difference of hydrophilicity/hydrophobicity between the bottoms of the first and second recesses and a surface of the photoresist layer, in combination with altitude differences, makes the red and green quantum dot materials to respectively form red and green quantum dot layers in the first and second recesses through autonomous flowing. The red and green quantum dot layers are excited by blue backlight source to respectively emit red light and green light, while the blue backlight source directly transmits through the transparent photoresist layers to give off blue light thereby providing three primary colors of red, green, and blue to achieve color displaying, increasing utilization of quantum dots, the effect of autonomous flowing of the quantum dot paste being made better for high…
