Abstract:
1. A mask for curing frame sealant having a transparent substrate, the transparent substrate comprising: a shading region formed on the transparent substrate and a transparent region adjacent to the shading region as well as a gradient shading region formed in a joining area between the shading region and the transparent region, wherein the gradient shading region is formed integrally and connects to the shading region; when the mask is utilized for exposure, an irradiation transmittance in the gradient shading region is smaller than an irradiation transmittance in the transparent region, but the irradiation transmittance in the gradient shading region is higher than an irradiation transmittance in the shading region; as a distance is increased between the gradient shading region and the shading region, a density of the gradient shading region is gradually decreased, so that the irradiation transmittance in the gradient shading region is linearly changed, wherein the frame sealant is coated on a surface of a first substrate, the gradient shading region of the mask being aligned to and overlapping the frame sealant in a direction perpendicular to the surface of the first substrate.
