Abstract
The present invention provides a curved display manufacturing method which can prevent phenomenon that outer surface edges of substrates are broken or pared unevenly while etchant is being injected, a curved display panel manufacturing using the same, and a curved display panel manufactured by the same. For this, a curved display panel manufacturing apparatus includes: an etching portion for partially paring outer portions of a first substrate and a second substrate such that thicknesses thereof are reduced to predetermined thicknesses; and a bending portion for bending the partially pared flat liquid crystal panel to a desired curved shape. The etching portion includes: at least one edge protection cover which is disposed on outer surface edge of the first substrate and the second substrate; and an injection nozzle which injects etchant to outer surfaces of the first substrate and the second substrate and to the edge protection cover.
