Disclosed is a production method for a bezel for display panels, whereby unnecessary material costs are reduced, a three dimensional surface shape can easily be imparted and deformation can be minimized. The production method for a bezel for display panels according to the present invention comprises the steps of: (a) providing a lower mould formed so as to have a three-dimensional pattern for imparting the surface shape of the bezel at the molding surface; (b) fastening a gasket to the molding-surface edge of the lower mould; (c) fasten an upper mould, which is provided with a raw-material injection part, on the gasket on the lower mould; (d) injecting a polymeric raw material for the bezel via the raw-material injection part of the upper mould; and (e) transferring the three-dimensional pattern formed in the molding surface of the lower mould, while curing the polymeric raw material.
