A flat panel display with a built-in touch panel includes a display panel having a lower substrate, an upper substrate, and a plurality of touch sensing patterns on the upper substrate. The plurality of touch sensing patterns includes a plurality of sensing cells on a bottom surface of the upper substrate that faces the lower substrate, a plurality of outer lines on the bottom surface of the upper substrate that connect lines of sensing cells of the plurality of sensing cells along at least one of a first direction or a second direction to a driving circuit, a plurality of connection lines that correspond to respective outer lines on the lower substrate. The plurality of outer lines are connected to the driving circuit via the plurality of connection lines on the lower substrate, and the plurality of outer lines are electrically connected to the corresponding connection lines.
