  • Patent number: 11864409
    Abstract: A light-emitting unit (140) is formed over a first surface (102) of a substrate (100). A first terminal (112) and a second terminal (132) are formed on the first surface (102) of the substrate (100), and are electrically connected to the light-emitting unit (140). A sealing layer (200) is formed over the first surface (102) of the substrate (100), and seals the light-emitting unit (140). In addition, the sealing layer (200) does not cover the first terminal (112) and the second terminal (132). A cover layer (210) is formed over the sealing layer (200), and is formed of a material different from that of the cover layer (210). In at least a portion of a region located next to the first terminal (112) and a region located next to the second terminal (132), a portion of an end of the cover layer (210) protrudes from the sealing layer (200).
