An exemplary display device includes a rear housing, a front frame, a display module, a connecting assembly pivotally connecting the front frame to the rear housing, a latching member, a slidable key, and a clamping member. The clamping member forms a latching block latched to the latching member for securing the front frame to the rear housing. The display module can be detached from the front frame and the rear housing by operating the slidable key. Correspondingly, the latching of the latching block and the latching member can be released.
