A method of manufacturing a touch screen panel includes forming first sensing electrodes on a first substrate, forming second sensing electrodes on a second substrate, and forming a photosensitive layer on the first sensing electrodes. The photosensitive layer is patterned to form photosensitive spacers spaced apart from one another in a first direction. The first substrate and the second substrate are joined together. The photosensitive spacers maintain a substantially constant space between the first sensing electrodes and the second sensing electrodes in a second direction.
