Beschreibung
Zusammenfassung:	The embodiment of the invention provides a polaroid, a display module and a display device.The polaroid is applied to the display module and comprises a first surface and a second surface which are oppositely arranged in the thickness direction, the thickness of the middle part of the polaroid is larger than that of the edge part of the polaroid, and the edge part is provided with a waterproof area; the waterproof area is provided with a groove, and an opening of the groove deviates from the second surface. By adopting the unequal-thickness design for the polaroid, the thickness of the middle part of the polaroid is larger than that of the edge part of the polaroid, and the edge part is provided with the waterproof groove, so that the overall thickness of the display module can be reduced after the polaroid is applied to the display module, and the design requirement for lightening and thinning is met; the waterproof performance of the polaroid can be improved, the problems that the polaroid is prone to losin
