An electronic device, comprising: a body, comprising a first surface and a second surface that are opposite to each other, as well as a lateral surface, the lateral surface being adjacent to the first surface and the second surface; and a flexible display module, comprising a first display portion and a second display portion that are integrated, the flexible display module being switchable between a retracted state and a sliding-out state, wherein, when the flexible display module is in the retracted state, the first display portion covers the first surface and the lateral surface, and the second display portion covers at least part of the second surface; and when the flexible display module is switched from the retracted state to the sliding-out state, the first display portion is adapted to slide along a direction where a free end thereof gets close to the lateral surface to expose a hidden region of the first surface; wherein, when the flexible display module is switched from the retracted state to the sliding-out state, the second display portion and the second surface are kept static, characterized in that the body comprises: a main body, surfaces of the main body forming the first surface and the second surface; and a moving body connected with the main body, a surface, far away from the main body, of the moving body forming the lateral surface, wherein, when the flexible display module is in the retracted state, the moving body is pressed against the main body; and when the flexible display module is in the sliding-out state, the moving body is separated from the main body. a body, comprising a first surface and a second surface that are opposite to each other, as well as a lateral surface, the lateral surface being adjacent to the first surface and the second surface; and a flexible display module, comprising a first display portion and a second display portion that are integrated, the flexible display module being switchable between a retracted state and a sliding-out state, wherein, when the flexible display module is in the retracted state, the first display portion covers the first surface and the lateral surface, and the second display portion covers at least part of the second surface; and when the flexible display module is switched from the retracted state to the sliding-out state, the first display portion is adapted to slide along a direction where a free end thereof gets close to the lateral surface to expose a hidden region of the first surface; wherein, when the flexible display module is switched from the retracted state to the sliding-out state, the second display portion and the second surface are kept static, characterized in that the body comprises: a main body, surfaces of the main body forming the first surface and the second surface; and a moving body connected with the main body, a surface, far away from the main body, of the moving body forming the lateral surface, wherein, when the flexible display module is in the retracted state, the moving body is pressed against the main body; and when the flexible display module is in the sliding-out state, the moving body is separated from the main body. a main body, surfaces of the main body forming the first surface and the second surface; and a moving body connected with the main body, a surface, far away from the main body, of the moving body forming the lateral surface, wherein, when the flexible display module is in the retracted state, the moving body is pressed against the main body; and when the flexible display module is in the sliding-out state, the moving body is separated from the main body.
