Touch display panel, and display device
A touch display panel includes: an embedded touch liquid crystal display (LCD) module, a polarizer, and a cover plate. The embedded touch LCD module includes a non-filter window. The polarizer is disposed over the embedded touch LCD module. The polarizer includes a polarizing layer, and the polarizing layer includes a base layer and a dichroic absorption layer disposed in the base layer. The dichroic layer has a non-polarized window, and the first vertical projection of the non-polarized window overlaps with the second vertical projection of the non-filtering window. The cover plate covers the polarizer. The disclosure also provides a method for manufacturing the touch display panel and a display device including the touch display panel.
