According to one embodiment, a display device includes a display module and a stand having a tilt mechanism which adjusts an upright angle of the display module. The tilt mechanism includes a fixed portion provided on the stand, a movable portion provided on the display module, a hinge shaft which pivotably couples the fixed portion and the movable portion together, and a lock member which limits pivoting of the movable portion with respect to the fixed portion. The lock member is movable between a lock position where the lock member engages with the movable portion so as to prevent the display module from falling down through at least a predetermined angle and a release position where the lock member leaves the movable portion so as to allow the display module to pivot freely.
