The invention provides a touch display panel and a touch
display device. The
transmittance of an optical filtering unit corresponding to any subpixel in a first column of subpixels of the touch display panel is smaller than that of optical filtering units corresponding to subpixels of the same row in the nth column of subpixels in the row direction; in addition, the first column of subpixels are positioned at one side, where the friction direction of touch electrodes in an alignment layer is in the row direction, of the bias direction, namely a clearance is formed between every two adjacent touch electrodes in the row direction; the
transmittance of the optical filtering unit corresponding to the subpixel close to one side of the clearance is smaller than that of the optical filtering unit corresponding to the subpixel at the other side in the same row; the optical filtering unit with low
transmittance is positioned at one side, where the friction direction of the clearance in the alignment layer is in the row direction, of the bias direction. When the optical filtering unit with low transmittance corresponds to the friction alignment layer, a friction abnormal area is generated at the clearance, so that the
visibility of the clearance is reduced when a frame is displayed, and the display effect is improved.
