封止樹脂を充填したことを特徴とする。 To summarize, this idea uses a glass substrate instead of a resin outer film, omit the transparent resin base, forms a transparent conductive film directly on one glass substrate, and places a back electrode on the transparent conductive film of this glass substrate. A laminate having at least a phosphor layer formed thereon is thermocompression-bonded with the side surface of the phosphor layer, a second glass substrate is placed on the back electrode side, and the first and second glass substrates are bonded together. It is characterized in that the gap formed between the substrate and the laminate is filled with a sealing resin.

する。 In other words, the transmittance is improved by omitting the transparent resin base, the transmittance is improved by replacing the resin outer film with a glass substrate, and the transparent conductive film is formed by forming a NESA film on the glass substrate instead of a transparent conductive film by vapor deposition. Due to the improvement in transmittance caused by this, the luminance can be improved by about 20 to 30% even if the same phosphor layer is used. Furthermore, by using a glass substrate instead of the resin outer film, moisture resistance is improved and the life span is improved by about 10 to 20%.
