A display device is provided, including: a housing body, a first shaft, a first roller, a flexible display screen, a main board, and a flexible circuit board. When the display device is in use, the entire flexible display screen is stretched to an exterior of the housing body. When the display device is idle, the flexible display screen is rolled up to be spirally sleeved on the roller. Therefore, a size of the display device can be reduced, and portability of the display device is improved.
