The sealing structure of the conventional EL display panel mentioned above is
Since a chip tube is used, a considerable amount of force is required when crushing it, and the force tends to vary, making it impossible to seal the injection port reliably.
There is a problem in that the reliability of preventing element deterioration is reduced.
本考案の目的はこのような従来の問題点を解決
する膜薄EL表示パネルを提供することである。 The purpose of the present invention is to provide a thin film EL display panel that solves these conventional problems.

According to the present invention, the above-mentioned conventional problems can be solved by using a thin film EL in the envelope consisting of a light-transmitting front substrate and a back plate.
A thin film EL panel with a built-in element and a protective fluid sealed in the envelope, characterized in that the inlet for sealing the protective fluid is sealed with a screw.
Solved by EL panel.

口にネジ７をねじ込んで封止する。 In the present invention, as shown in Figs. 1 and 2, a tip tube 6' with a threaded hole is used instead of the conventional tip tube 6, and after filling the protective fluid, a screw 7 is screwed into the injection port. Seal with.
このように封止にネジを使つているので、封入
の為の力を余り必要とせず、しかもネジを締めつ
けて封止するので外気が内部へ入りにくくなる。 Since screws are used for sealing in this way, much force is not required for sealing, and since the screws are tightened to seal, it is difficult for outside air to enter the interior.
