Abstract
In a mask for hardening a sealant and a method of manufacturing a flat display device using the mask, the mask includes a main body in which a transmission slit is formed, and a partial shielding portion partially shielding the transmission slit. The transmission slit corresponds to the shape of the sealant enclosing a light-emitting portion formed on a substrate. By using such a mask, the partial shielding portion covers a portion where the amount of laser irradiation is relatively large, thus hardening the sealant uniformly across the entire regions of the sealant, and thus guaranteeing a stable encapsulating structure.
Claims19
A mask for hardening a sealant, the mask comprising:
- a transmission slit geometrically corresponding to a shape of a sealant enclosing a light-emitting portion formed on a substrate and including a plurality of straight line portions connected together by intermediate corner portions;
- and
- a partial shielding portion disposed in corresponding ones of the corner portions to partially shield the transmission slit.
A method of manufacturing a flat display panel, the method comprising the steps of:
- applying a sealant around a light-emitting portion formed on a substrate, and covering the sealant with an encapsulating substrate;
- installing a mask for hardening the sealant on the encapsulating substrate, the mask comprising a transmission slit which geometrically corresponds to a shape of the sealant and a partial shielding portion partially shielding the transmission slit;
- and
- hardening the sealant by irradiating laser onto the sealant through the transmission slit.
