A display device, comprising a backlight module (1), a display module (2) located on the light emitting surface side of the backlight module (1), a grating selector (3) located between the backlight module (1) and the display module (2), and a light modulating unit (4) provided on the light emitting surface side of the display module (2). The display module (2) comprises: a pixel array, which comprises a plurality of pixels (22), the pixels (22) each having a plurality of blocks; and a grating micro structure (21), which is used for controlling each block of each pixel (22) to emit light in a different direction. The grating selector (3) is used for controlling the light emitted by the backlight module (1) to irradiate the corresponding blocks of the pixels (22), such that the pixels (22) emit light in a particular direction. The light modulating unit (4) is used for modulating the direction of the light emitted by the pixels (22) in a particular direction, such that the picture displayed by the display device is visible at a particular angle.
