Abstract: A touch display apparatus with a display region and a frame region is provided. The touch display apparatus includes a base substrate, a display function layer and a thin film encapsulation layer which are sequentially stacked. The display function layer is located in the display region. A touch electrode layer is arranged at a side, facing away from the base substrate, of the display function layer. The frame region includes a slope region adjacent to the display region. The thickness of the touch display apparatus in the slope region is gradually decreased outward from the display region. The touch electrode layer includes touch electrodes which form a grid of metallic wires. The grid density of the touch electrodes in the slope region is higher than that in the display region.
