Patent ID: 8242693

Claim:
A package structure of a light emitting device, the package structure comprising: a device substrate having an active region and a peripheral region surrounding the active region at least a light emitting device disposed in the active region of the device substrate; and a cover structure comprising: a cover substrate having an active region and a peripheral region surrounding the active region, wherein the active region of the cover substrate corresponds to the active region of the device substrate, and the peripheral region of the cover substrate corresponds to the peripheral region of the device substrate; a blocking dam disposed in the peripheral region of the cover substrate and facing the device substrate, wherein the blocking dam substantially surrounds the active region of the cover substrate; a sealant disposed in the peripheral region of the cover substrate and facing the device substrate, wherein the sealant substantially surrounds the blocking dam, and the cover substrate is bonded to the device substrate through the sealant; a buffer space, disposed between the blocking dam and the sealant, and between the cover substrate and the device substrate; and an encapsulation glue, wherein the encapsulation glue is blocked by the blocking dam and substantially in the active region of the cover substrate, and the encapsulation glue covers at least a part of the light emitting device.
