Provided is a method for manufacturing a curved display by which a display module that has a tap for electrical connection is manufactured into the curved display, the method including: a step of sealing a circumference of the display module excluding a part of the tap which projects outward from the display module with a sealing material having acid resistance; a step of performing masking by using a masking member to surround either a pair of left and right sides or a pair of upper and lower sides facing each other in the sealed display module; a step of etching the display module, excluding the masked part of the masked display module, into a preset thickness such that the thickness of the display module is decreased; a step of removing the masking member from the display module that is etched in the etching step; and a step of bending the display module from which the masking member is removed into the curved surface.
