Abstract

An edge narrowing method for a display panel is disclosed. The method includes the steps of providing the display panel, a grinding apparatus and a polishing apparatus; tilting the display panel so that the first substrate and a grinding member of the grinding apparatus have a first grinding angle therebetween; grinding the first substrate and the light-shielding area with the grinding apparatus while the display panel is tilted at the first grinding angle, thereby forming a first grinding end surface; stopping grinding of the first substrate and the light-shielding area when the width of the light-shielding area is between 0.35 and 1 mm; and polishing the first grinding end surface with the polishing apparatus to form a first end surface.
