UV mask and fabrication method thereof

摘要

A UV mask and a fabrication method thereof. The UV mask fabrication method includes: forming a UV shielding layer on a coverage area of a base substrate by using a color filter layer mask plate and a black matrix mask plate; or forming a UV shielding layer on the base substrate by using the color filter layer mask plate. In this way, the cost spent in manufacturing a display device by using a special mask plate (mask) to fabricate the UV mask is reduced.

1. A manufacturing method of a UV mask, the UV mask used for UV curing a sealant in a display panel, and the method comprises:
forming a UV light-shielding layer on a covering region of a base substrate by using a color filter layer mask and a black matrix mask; or, forming a UV light-shielding layer on the base substrate by the color filter layer mask; wherein the base substrate on which the UV light-shielding layer is formed is hanged over the display panel; wherein the covering region of the base substrate is configured to include a display region corresponding to an effective display region in the display panel and an edge region surrounding the display region; a boundary line of the edge region that is close to the display region coincides with a boundary line of the display region, and under a case in that the display region is positioned to align with the effective display region of the display panel, the edge region is positioned between the effective display region of the display panel and the sealant; wherein the forming the UV light-shielding layer on the base substrate by a color filter layer mask comprises: forming a pattern of a first UV light-shielding layer, wherein a pattern of a first region, a pattern of a second region and a pattern of a third region are formed on the covering region of the base substrate by at least one of a red color filter layer mask, a green color filter layer mask and a blue color filter layer mask; forming a pattern of a second UV light-shielding layer, wherein the second UV light-shielding layer is formed in gaps between the pattern of the first region, the pattern of the second region and the pattern of the third region on the base substrate by the red color filter layer mask or the green color filter layer mask or the blue color filter layer mask.
