Abstract
The present invention provides an in-cell touch display panel. In the in-cell touch display panel of the present invention, a first planarization layer (14) is solely arranged between a pixel electrode (15) and source/drain electrodes (45) located on one side of a TFT substrate (1) and the pixel electrode (15) is connected through a second via (141) formed in the first planarization layer (14) to the source/drain electrodes (45) so that compared to the prior art, the thickness of two passivation layers is omitted between the pixel electrode (15) and the source/drain electrodes (45) and negative influence caused by overlapping of vias between the first passivation layer (16) and the first planarization layer (14) and between the second passivation layer (18) and the first planarization layer (14) can be eliminated, whereby there is no need to take into consideration the relationship of the first planarization layer with respect to the first passivation layer and the second passivation layer in making a design so that the aperture ratio of the pixel can be greatly increased. Further, since the number of vias formed is reduced, the structure is simple and the manufacturing difficulty is lowered down to thereby improve product yield.
