The invention is applicable to the technical field of support devices and provides an angle adjustment structure and a display. The angle adjustment structure comprises a first hinge seat for being fixed to a support, a damping rod mounted to the first hinge seat, and a second hinge seat for being fixedly connected with a display screen and rotationally connected to the damping rod to adjust the pitch angle of the display screen. The second hinge seat is provided with a conical hole with the axis parallel to the axial direction of the damping rod. The angle adjustment structure further comprises a stopping piece located in the conical hole and an adjustment rod fixedly connected with the stopping piece and used for adjusting the position of the stopping piece in the axial direction of the conical hole. The angle adjustment structure can change the adjustment range of the pitch angle of the display screen, when the display is put at a special position, a large pitch angle can still be obtained by adjustment, and viewing experience of users is improved.
