A fabricating method of a touch screen panel, a transparent electrode layer and an insulating layer which are sequentially formed on a same surface of a transparent substrate. The transparent electrode layer and the insulating layer are co-patterned using a halftone mask to form a plurality of first sensing patterns connected along a first direction, a plurality of second sensing patterns having separated patterns between the first sensing patterns, and the insulating layer positioned on the first and second sensing patterns to expose regions of the second sensing patterns. A conductive layer is formed on the transparent substrate on which the first and second sensing patterns and the insulating layer are formed. The conductive layer is patterned to form second connection patterns allowing the second sensing patterns to be connected along a second direction through the exposed regions of the second sensing patterns.
