Abstract
A manufacturing method of a mask plate for shielding during sealant-curing includes: forming a negative photoresist light-shielding material layer on a transparent substrate; with a color-filter mask plate set, exposing the substrate formed with the negative photoresist light-shielding material layer; developing the substrate after exposing to form the pattern of the mask plate. The method does not require separate fabrication of a mask plate, thereby significantly reducing the manufacturing costs of the mask plate for shielding during sealant-curing.
