The invention discloses a laser cutting method and device, a polaroid and a display screen, relates to the technical field of laser cutting, and aims to solve the problems that the cutting section of a laser cutting film material in the prior art is uneven, a surface layer and a bottom layer are difficult to tear and separate, and the precision of a heat effect area is low. The laser cutting method and device are applied to cutting of a membrane material, the membrane material comprises multiple stacked material layers, the laser cutting method comprises the steps that the membrane material is cut multiple times till the membrane material is cut through, and the cutting parameter of each time of cutting is matched with the material attribute of the material layer to be cut; a laser cutting method is applied to the device. The polaroid is obtained through a laser cutting method. The display screen comprises a display panel and a polaroid stacked on the display panel. In conclusion, the cutting section of the m
