The utility model relates to a two-dimensional code display device, and the device comprises a display screen module which comprises a plurality of lamp beads distributed in an array, a control module and a display panel, and the control module is used for controlling and lightening the lamp beads in each row to generate a two-dimensional code, and displaying the two-dimensional code on the display panel; and the transparent light-staying film is arranged on the display panel. The structure is simple, the transparent light-standing film is arranged on the display panel, when the low-refresh-rate display screen module lightens the lamp beads in each row to dynamically generate the two-dimensional code, the positions of the lighted lamp beads in the last round are kept at certain brightness for a period of time, namely, point position light displayed in the last round can stay for a short time, and the two-dimensional code can be dynamically generated. The definition of the two-dimensional code dynamically gene
