Barrier wall of color filter, its manufacturing method, and color filter

A manufacturing method for a barrier wall of a color filter, comprising the steps of.

• providing a transparent substrate;
• forming a first photoresist layer on the substrate, the first photoresist layer comprising a polysiloxane or its derivative, the polysiloxane or its derivative containing at least one repeating unit represented by the following formula
• wherein R1 and R2 can each represent a separate alkyl or phenyl;
• arranging a photomask between the first photoresist layer and a light source and exposing the first photoresist layer;
• and
• developing the first photoresist layer and forming the first barrier wall.

• developing the photoresist layer and forming the barrier wall;
• forming a second photoresist layer on an outer surface of the barrier wall, the second photoresist layer comprising a polysiloxane or its derivative, the polysiloxane or its derivative containing at least one repeating unit represented by the following formula
• wherein R1 and R2 can each separately represent an alkyl or phenyl group;
• and
• solidifying the second photoresist layer.
