There is provided a flexible touch screen panel capable of being bent or folded. The flexible touch screen panel includes a film substrate and sensing electrodes formed in an active area of at least one surface of the film substrate. The film substrate is divided into a plurality regions so that elongation ratios differ between regions of the film substrate. Also provided is a method of manufacturing a flexible touch screen panel including providing a supporting substrate including a plurality of distinct regions, coating a plurality of film materials onto the supporting substrate, the distinct regions of the supporting substrate being coated with different film materials, hardening the film materials to form a film substrate, forming touch sensing patterns including sensing electrodes on the film substrate, and separating the supporting substrate and the film substrate from each other.
