Light emitting unit having an encapsulation unit
First Claim
Patent Images
1. A light emitting device comprising:
- a substrate;
a light emitting unit on the substrate; and
an encapsulation unit having a first region corresponding to the light emitting unit and a second region outside of the first region to couple with the substrate via a sealant, the second region being coupled at a periphery of the substrate,wherein the encapsulation unit at the first region includes a central area and an edge area, the edge area having a flat shape or a straight-line shape, and the edge area being provided about the central area such that the edge area is adjacent the second region, andwherein the edge area extends from an inner edge of the second region to a region aligned with one end of the light emitting unit, andwherein the central area has a positive curvature that projects away from the substrate.
