Abstract
The present invention includes a frame-shaped sealing material, a filling layer, and a support. The frame-shaped sealing material is provided between a TFT substrate and a counter substrate, and is configured to seal an organic EL element (electroluminescent element) along with the TFT substrate and the counter substrate. The filling layer is composed of a liquid filler, and is filled in the space between the counter substrate, a sealing film, and the sealing material. The support is located inside the sealing material and between the TFT substrate and the counter substrate, and also supports the TFT substrate and the counter substrate.
