  • Publication number: 20200235332
    Abstract: In the present embodiment, a sealing agent (50) sealing two substates contains a low melting-point glass material and is adhered to each of a first substrate (10) and a second substrate (20), a barrier rib (60), which is formed in such a manner as to surround the outer periphery of an electronic element (30), is disposed between the sealing agent (50) and the electronic element (30), and between the first substrate (10) and the second substrate (20), and the sealing agent (50) is spaced apart from the barrier rib (60). As a result, a deterioration of the electronic element, caused by the heat produced when sealing, may be prevented while the electronic element formed between the two substrates is protected from moisture and oxygen.
