画面を構成しようとするものがある（例えば、特開昭５
９−５０４２５号公報）。However, when trying to construct such a large liquid crystal display device using a large glass substrate that can accommodate an ultra-large screen,
This was impossible due to technical difficulties in controlling the gap between the substrates where the liquid crystal is sealed and injecting the liquid crystal. Therefore, there are devices that attempt to construct a large screen by using liquid crystal panels, which have traditionally been widely used in watches and calculators, as unit liquid crystal units, arranging many of them on the same plane and connecting them (for example, Japanese Patent Application Publication No. 5
9-50425).

It appears as a blank line from the front like a frame, and the displayed image becomes unsightly. Another problem was that the depth needed to be effectively illuminated by the backlight, making it impossible to adapt to thinner designs.
そこで本発明の目的は、薄型で超大型の液晶パネルの形

It's about making it easy.
