Colored filter with spacer, liquid crystal display device and method for making the same

The invention discloses a colorful optical filter base plate with fixed spacers and a manufacturing method thereof. The colorful optical filter comprises a transparent substrate, a colorful film layer, a latticed black matrix, a flat layer, a transparent electrode layer and a columnar spacer. Firstly, the well-known colorful optical filter base plate is coated with transparent photosensitive material and then exposed by a mask with preset patterns, after being treated by adopting micro-lithography, the transparent columnar or frustum-shaped spacers are directly formed on the colorful optical filter base plate; the central shafts of the spacers are perpendicular to the surface of the flat layer and corresponding to the intersection of gridlines of the black matrix. Since the spacers are directly formed on the colorful optical filter base plate and the height, distribution and density thereof are all preset and controllable, the liquid crystal thickness (CELL GAP) between LCD base plates can be kept uniform, thus avoiding arranging the spacers within a pixel to affect the porosity of LCD.
