Abstract
A touch display panel and a display apparatus are provided. The touch display panel includes: a first substrate, a second substrate, a common electrode layer, a touch electrode layer and a touch electrode wire layer. The common electrode layer is an entire piece of electrode; thus, respective display units may be ensured to have the same common voltage during a display driving, thereby solving the conventional problem of image flicker and non-uniform display of the display panel due to different common voltages in the respective display units caused by different resistances of the block-shaped electrodes in the common electrode layer. Moreover, the touch electrodes in the touch electrode layer are metal grid electrodes. Hence, the resistances of the touch electrodes are reduced and a touch sensitivity of the touch display panel is improved, while a high light transmittance of the touch display panel is ensured.
