Abstract: A touch display apparatus includes a display panel, a receiving container and a touch controller. The display panel includes a metal pattern. The metal pattern includes a gate metal pattern and a data metal pattern. The gate metal pattern includes a gate line extending in a first direction. The data metal pattern includes a data line extending in a second direction crossing the first direction. The display panel is configured to display an image. The receiving container receives the display panel and includes a metal. The touch controller includes a first connecting line electrically connected to the metal pattern and a second connecting line electrically connected to the receiving container. The touch controller is configured to sense change of capacitance due to change of difference between the metal pattern and the receiving container.
