    • PROBLEM TO BE SOLVED: To provide a thin film transistor panel and a display device, provided with a built-in sensing element capable of accurately sensing a contact and a contact position. SOLUTION: This display device includes a common electrode display panel having a common electrode disposed thereon; and a thin film transistor display panel including a thin film transistor provided with a gate electrode, a source electrode and a drain electrode, a lower protective film disposed on the source and drain electrodes, an upper protective film disposed on the lower protective film and including at least one sensing protrusion, pixel electrodes disposed on the upper protective film and connected with the drain electrode, and at least one conductive member disposed on the sensing protrusion. The sensing unit is installed within the display device and therefore the thickness and volume of the display device can be reduced, the fabrication process is simplified, and the fabrication cost can also be reduced. In addition, because the sensing protrusions are formed on the thin film transistor display panel as a lower display panel, durability of the sensing protrusions can be enhanced.
