Patent ID: 6844120

Claim:
A micro-fluidic manufacturing method of forming a color filter, comprising steps of: providing a transparent substrate with a plurality of black matrixes; forming a photoresist layer on the transparent substrate to cover the black matrix; and using lithography to pattern the photoresist layer as a plurality of strips of high-wall ribs and forming a plurality of ribs on the black matrixes respectively, wherein the width of the rib is not larger than the width of the black matrix, and wherein during lithography, the photoresist layer is patterned as a plurality of connecting ribs for connecting the strips of high-wall ribs, in which the height of the connecting rib is less than the height of the high-wall rib, and the width of the connecting rib is not larger than the width of the black matrix; injecting a plurality of micro fluids into a plurality of predetermined areas separated by the ribs, wherein the micro fluids within each predetermined area are driven and mixed by surface tension of fluids to serve as an ink; drying each ink within each predetermined area to form a plurality of color layers of different colors; removing the high-wall ribs and connecting ribs; and forming a transparent conductive layer on the transparent substrate to cover the black matrixes and the color layers.
