    Abstract: The present disclosure provides a display device comprising a display panel, wherein a first polarizer is arranged at a side of the display panel that is opposite to the side for displaying images, and a functional component with a grid structure and a second polarizer are arranged in sequence along the direction away from the display panel at the side for displaying images, the second polarizer being capable of scattering light rays that penetrate the second polarizer. In the above display device, the second polarizer is capable of scattering light rays that penetrate the second polarizer, such that certain degree of atomization is generated in the displayed images of the display device, which atomization can reduce the Moir é patterns caused by the interference between the pixels of the display panel and the grid structure of the functional component, thus eliminate the Moir é patterns in the display images, and improve the display effect; additionally, the atomization of the displayed images by the second polarizer can also eliminate the shadows formed under irradiation by light rays due to different reflectivities of the respective areas in the pattern of the grid structure of the functional component, thereby further improving the display effect of the display device.
