Abstract

A touch screen panel includes: a flat panel display including an upper substrate, a lower substrate, and pixels arranged on a display region of the lower substrate in a stripe arrangement; first sensing cells arranged in a first direction on the upper substrate and second sensing cells arranged in a second direction on the upper substrate; first connection patterns electrically connecting adjacent ones of the first sensing cells to each other in the first direction, and second connection patterns electrically connecting adjacent ones of the second sensing cells to each other in the second direction, wherein at least one of the first connection patterns and the second connection patterns is inclined so that it partially overlaps with the pixels.
