Another aspect of the present disclosure provides a display device. The display device includes a display module. The display module includes a display panel, including a plurality of sub-pixels; and a pixel shift unit, disposed at a side of a light-exiting surface of the display panel. Light emitted by the plurality of sub-pixels exits after passing through the pixel shift unit. For a sub-pixel of the plurality of sub-pixels: at a first time, the pixel shift unit does not shift the light emitted by the sub-pixel, and after the light emitted by the sub-pixel passing through the pixel shift unit, a first display pixel is formed corresponding to the sub-pixel at the first time, and at a second time, the pixel shift unit shifts the light emitted by the sub-pixel, and after the light emitted by the sub-pixel passing through the pixel shift unit, a second display pixel is formed corresponding to the sub-pixel at the second time. The second display pixel does not overlap the first display pixel. An orthographic projection of the second display pixel corresponding to the sub-pixel overlaps an orthographic projection of a first display pixel of at least one adjacent sub-pixel of the plurality of sub-pixels. For the first display pixel and second display pixel having overlapped orthographic projections, the orthographic projection of the first display pixel is located inside the orthographic projection of the second display pixel, or the orthographic projection of the second display pixel is located inside the orthographic projection of the first display pixel. For the first display pixel and second display pixel having overlapped orthographic projections, a sub-pixel of the plurality of sub-pixels, corresponding to the first display pixel, and another sub-pixel of the plurality of sub-pixels, corresponding to the second display pixel, have different colors.
