Mother panel wherein a sealing material includes a first sealing material and a second sealing material wherein the first and second sealing material enables air tight sealing within a periphery of the mother panel
View Patent ↗A mother TFT substrate having plural TFT substrates, and a mother counter substrate having plural counter substrates are bonded together to form a mother panel. At this time, the interior of the mother panel is sealed only with a sealing material, without forming a sealant separately in seal portions. The mother counter substrate has plural counter substrates of liquid crystal cells. A sealing material is arranged in two rows surrounding the counter substrates in the periphery of the mother counter substrate, except for the seal portions in which seal portion sealing materials are arranged in two rows in a staggered manner on the short sides. When the mother counter substrate and the mother TFT substrate are overlapped and the inside air is let out, the sealing materials are heated. Then, the seal portion sealing materials are bridged together to seal the interior of the mother panel.

a mother TFT substrate;
a mother counter substrate bonded to the mother TFT substrate; and
a plurality of liquid crystal cells;
wherein the mother TFT substrate and the mother counter substrate are bonded together with a sealing material provided in the periphery surrounding the plurality of liquid crystal cells;
wherein the sealing material includes a first sealing material of a seal portion in the periphery as well as a second sealing material of an other portion in the periphery so as to enable air tight sealing within the periphery of an interior of the bonded together mother TFT substrate and the mother counter substrate forming the mother panel and containing the plurality of liquid crystal cells therein;
wherein the second sealing material of the other portion in the periphery is arranged in two rows;
wherein the first sealing material of the seal portion in the periphery is arranged in at least one row; and
wherein no sealant other than the first sealing material is formed in the seal portion in the periphery so as to enable the air tight sealing in the periphery of the mother panel.
2. A mother panel comprising:
