Method for manufacturing color filters by micro fluid

There is provided a method for manufacturing color filters by micro fluid, which includes the steps of: providing a transparent substrate formed thereon a plurality of black matrices; forming a plurality of barrier walls on the black matrices of the substrate wherein the width of each barrier wall is smaller than the width of the black matrix; respectively filling a plurality of micro fluids with required colors between every two barrier walls, wherein the plurality of micro fluids are combined into an ink between the barrier walls; curing the inks of different colors between every two barrier walls, and respectively forming a plurality of color layers of the required colors between every two barrier walls; removing the plurality of barrier walls on the black matrices of the transparent substrate; and forming a transparent conductive layer on the transparent substrate for covering the black matrices and color layers.
