摘要： A method of manufacturing a color filter for a reflective liquid crystal display is disclosed. The method comprises the following steps: 1) coating a layer of positive photoresist on a reflective layer or reflective substrate, and exposing the photoresist layer to a light via a mask having a fine pixel pattern so as to form at least three exposed regions of different exposed energy in the photoresist layer, 2) Removing one of the existing exposed regions having a largest exposed dose by the use of an alkaline developer solution so as to expose the surface of the electrically conductive reflective substrate corresponding to the removed region; and electrodepositing a color paint on the exposed surface of the reflective substrate to form a color filter layer of one selected color, 3) repeating step 2) to remove the other exposed regions in the photoresist layer and proceeding with an electrodeposition process with another color paint until a color filter layer of all desired colors is completed. Thus, a color filter for a reflective crystal display according to the present method could obtain a uniform thickness, a better flatness, and a pattern of high fineness and have a large degree of freedom in pattern arrangement and the possibility of increased size.

摘要： Color layers of a color filter obtained by exposing a transparent substrate to light from the back side followed by development may have a defect of layer unflatness produced due to unevenness caused by contamination with foreign matters. The defect can be repaired by eliminating the defective part of the color layers to produce a blank there, optionally filling the blank with a negative photosensitive composition containing a black colorant and returning the thus modified color filter to an appropriate step in the production line. The color filter repaired is used to fablicate multi-color display devices which are by no means inferior in display qualities to those fablicated using a color filter having no defect originally.
