A display having pivot constraint function is disclosed in the present invention. The display includes a panel, a supporter, a pivot mechanism and a constraint mechanism. The pivot mechanism is disposed between a first bridging component of the panel and a second bridging component of the supporter. A rotation angle of the panel relative to the supporter can be adjusted via the pivot mechanism, and the constraint mechanism can constrain the rotation of the panel relative to the supporter. The constraint mechanism includes a body and a contacting portion. The body is movably disposed on the panel, and partly protrudes from a boundary of the panel. The contacting portion is connected to the body for simultaneously contacting the first bridging component and the second bridging component, so as to constrain rotation between the first bridging component and the second bridging component, and to fix a view angle of the panel.
