Seal Design for Liquid Crystal Display

Disclosed is a liquid crystal display (LCD) with a surrounding seal device which has an isolation capability of a connection material (CM) and a suppression capability of liquid crystal (LC) penetration.

A LCD shown in Fig. 1 consists of a surrounding seal 6, an opening slit for LC insertion 3 and a display area 4 which are sandwiched by two glass substrates.

This surrounding seal device comprises CM isolation walls 7 and a LC stopping wall 8.

When the CM is sandwiched and pressed by two glass substrates, the CM is spread into the glass substrates. There is a possibility that the spread CM causes short circuits of display electrodes. But, by using the CM isolation walls 7, the spread CM is led to the outer space of the surrounding seal 6 and it will isolate itself from the display area 4 and electrodes.

When the LC is inserted from the opening slit 3, the LC is penetrated into the outer space of the surrounding seal 6. However, the LC stopping wall 8 suppresses the LC penetration.
