Capacitive in-cell touch panel and display device

The invention discloses a capacitive in-cell touch panel and a display device. A transparent touch sensing structure layer is arranged on one side, facing towards a liquid crystal layer, of an opposite substrate opposite to an array substrate, and comprises first touch sensing electrodes and second touch sensing electrodes, wherein the first touch sensing electrodes and the second touch sensing electrodes are arranged in the same layer and mutually isolated. Mutual interference between a touch signal and a display signal in the array substrate can be avoided due to the fact that the touch sensing structure layer realizing touch is arranged on the opposite substrate far away from the array substrate; the quality of liquid crystal display frames is ensured; and the reliability of touch operation is improved. In addition, since the first touch sensing electrodes and the second touch sensing electrodes are arranged in the same layer in the touch sensing structure layer arranged on the opposite substrate, compared with that two layers of strip electrodes mutually crossed in different surfaces are manufactured respectively to serve as the touch sensing structure layer, the structure is relatively simple; the preparation technology steps can be shortened; and the production cost can be lowered.
