Claim:
1. A method for narrowing edges of a display panel, the display panel comprising a first substrate, a second substrate, a sealant and a light-shielding area, the sealant being disposed between the first substrate and the second substrate, the light-shielding area being disposed between the sealant and the first substrate, the method comprising: providing the display panel; tilting the display panel so that the first substrate of the display panel and a horizontal plane form a first tilt angle therebetween; grinding the first substrate and the light-shielding area to form a first grinding end surface on the first substrate and the light-shielding area while the display panel is tilted at the first tilt angle; and polishing the first grinding end surface to form a first end surface; wherein an arithmetic average roughness Ra of the first end surface is between 0.001 and 0.04 μm, and a maximum roughness height Ry of the first end surface is between approximately 0.1 and 0.5 μm.
