Abstract
A touch screen panel includes a transparent substrate; a plurality of first sensing patterns at a first side of the transparent substrate and coupled to each other along a first direction; a plurality of second sensing patterns at the first side of the transparent substrate and coupled to each other along a second direction, the second sensing patterns being alternately arranged with the first sensing patterns not to overlap with the first sensing patterns; and a phase difference compensating layer at the first side of the transparent substrate and adapted to compensate for a birefringence phase difference of a liquid crystal layer in a liquid crystal display panel at a second side of the transparent substrate.
