Abstract

The invention provides a touch displaying device and substrate. A plurality of data lines, a plurality of gate lines, a plurality of pixel electrodes, a plurality of common electrodes and covering electrodes are included. The gate lines and the data lines are in insulation crossing. In the extending direction of the gate lines and/or the data lines, a carving seam is formed between two adjacent common electrodes. The covering electrodes are placed above the carving seams. At a displaying stage, common voltage is applied to the covering electrodes. The projection of the carving seams on the touch displaying substrate and the projection of the data lines and/or the gate lines on the touch displaying substrate comprise coinciding parts. The projection of the covering electrodes on the touch displaying substrate at least covers the data lines and/or the gate lines of the coinciding parts. Accordingly, voltage fluctuation on the data lines and/or scanning lines can be screened through the covering electrodes, and the problems of light leakage and poor image displaying effect caused by voltage fluctuation are solved.
