A method for manufacturing a curved-surface display having a desired curved shape using a flat display panel having a first substrate and a second substrate includes: paring partially outer surfaces of the first substrate and the second substrate so as to reduce thicknesses thereof to a predetermined thickness; attaching a polarizer on at least one of the pared outer surfaces of the first substrate and the second substrate; and attaching a reinforcing plate having the same shape with the desired curved shape and light transmitting characteristics to the display panel using an adhesive layer which is formed on at least a portion of edge portions of the display panel in a state that the pared flat display panel to which the polarizer is attached is bent to the desired curved shape.
