Methods of fabricating display panel and flexible color filter thereof

Abstract

A method of fabricating a display panel comprises the steps of: forming a controlling elements array substrate and a flexible color filter, respectively; forming a displaying medium on the controlling elements array substrate; and assembling the flexible color filter to the controlling elements array substrate for disposing it on the displaying medium layer. A method of fabricating a flexible color filter comprises the steps of: forming a flexible substrate on a rigidly substrate; forming a color filter film comprising a plurality of color filter patterns; and separating the flexible substrate from the rigidly substrate. Since the color filter film is formed before separating the flexible substrate from the rigid substrate, the flexible color filter may have good resolution and process yield.
