Abstract:
A method for manufacturing a color filter of a reflective type LCD, the color filter manufactured by utilizing dry film technology, the method comprising the steps of:(a) forming a plurality of first color layers on a substrate, in which the substrate is exposed and developed to form the first color layers on a first side of the substrate; (b) forming a plurality of second color layers on the substrate, in which the substrate is exposed and developed to form the second color layers on the first side of the substrate; (c) forming a plurality of third color layers on the substrate, in which the substrate is exposed and developed to form the third color layers on the first side of the substrate; and (d) forming a plurality of fourth color layers on the substrate, in which the substrate is exposed through an exposure area defined by a back mask disposed at a second side opposite to the first side, and then developed to form the fourth color layers on the substrate, wherein at least two of the first color layers, the second layers and the third color layers fall within the exposure area and act as an inherent mask.
