Method of fabricating light emitting body protection glass for quantum dot display

Abstract

A method for fabricating a light emitting body protection glass for a quantum dot (QD) display is disclosed, which fabricates a quantum dot (QD) hole having a minimum difference in width between a top surface and a bottom surface of the glass. The method includes a masking print step to mask a glass with UV ink to protect the remaining glass parts other than a QD hole, a masking dry step to dry a mask layer printed through the masking print process, an exposure step to UV-cure the mask layer other than the QD hole by irradiating UV light onto the mask layer to protect the glass parts other than the QD hole, a pre-bake step to dry the mask layer printed on the glass in a manner that the dried mask layer adheres closely to the glass, a development step to remove a non-UV-cured and non-exposure mask layer from the entire mask layer so that the glass located adjacent to the QD hole is exposed, a hard-bake step to dry the UV-cured mask layer that is less adhesive to the glass in the development step such that the dried mask layer adheres closely to the glass, a protection film lamination step to allow a protection film to be laminated on the glass located opposite to the QD hole; an etching step to spray etchant onto the glass such that the glass surface exposed by the development step is etched, a delamination step to remove the UV-cured mask layer from the glass surface after completion of the etching step, and a cleaning step to clean the glass. Thus, through execution of the above steps, the mask layer, that has a possibility of being loosely fastened to the glass surface in the exposure and development steps, adheres more closely to the glass surface, such that the QD hole formed by the etching step has a minimum difference in width between the glass surface and the QD-hole bottom surface.
