Sealed body, light-emitting module, and method of manufacturing sealed body

說明書
Alternatively, although not illustrated, the island-shaped or stripe-shaped high-reflectivity layer 206a and the island-shaped or stripe-shaped low-reflectivity layer 206b may be alternately provided over the first substrate 201. Furthermore, a layer which transmits the energy ray and to which the sealant 231 is easily welded may be provided over the island-shaped or stripe-shaped high-reflectivity layer 206a. For the layer to which the sealant 231 is easily welded, a material having high affinity with the sealant 231 is preferably used; for example, in the case where the sealant 231 is a low-melting-point glass; a layer containing silicon oxide is preferably used.
The sealant 231 provided over the high-reflectivity layer 206a or the low-reflectivity layer 206b is welded to the first substrate 201 and the second substrate 202. Note that an anchor layer may be provided to improve the welding strength between the first substrate 201 and the sealant 231. The anchor layer may be provided between the high-reflectivity layer 206a and the sealant 231 so as to be in contact with them, or may be provided between the low-reflectivity layer 206b and the sealant 231 so as to be in contact with them. Alternatively, an island-shaped or stripe-shaped anchor layer may be provided between the high-reflectivity region 205a and the low-reflectivity region 205b to improve the welding strength.
