摘要： A light emitting device (10) includes a substrate (100), an organic EL element (102), a buffer film (210), and a sealing film (220). The organic EL element (102) is formed over the substrate (100). The sealing film (220) is located over the substrate (100) and over the organic EL element (102), and seals the organic EL element (102). In addition, the buffer film (210) is located between the organic EL element (102) and the sealing film (220), and comes into close contact with the sealing film (220). The sealing film (220) includes at least one layer formed of, for example, an oxide.

摘要： A second electrode (150) is formed of a semi-transparent film. A light-transmitting film (210) and a reflective film (220) are formed on the second electrode (150). A laminated structure of the second electrode (150), the light-transmitting film (210), and the reflective film (220) is also formed between organic EL elements (lamination portion of a first electrode (110), an organic layer (140), and the second electrode (150)) adjacent to each other. A portion of external light entering a substrate (100) is reflected by the second electrode (150), and the remainder passes through the second electrode (150). Light passing through the second electrode (150) is reflected by the reflective film (220) through the light-transmitting film (210). A portion of this reflected light is emitted to the outside through the second electrode (150), but the remainder is reflected by the second electrode (150) and is directed to the reflective film (220) again.

摘要： 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).
