1. A method of manufacturing a flexible color filter having touch sensor integrated therein, comprising the steps of:
forming a separation layer by applying a composition for forming the separation layer on a carrier substrate;
forming a protective layer by applying a composition for forming the protective layer on the separation layer;
forming a black matrix (BM) layer on the protective layer;
forming a touch sensor layer on the BM layer;
forming a colorant layer on the touch sensor layer;
forming an insulation layer on the touch sensor layer and the colorant layer;
removing the carrier substrate; and
attaching a flexible base film on a side of the separation layer from which the carrier substrate is removed.
