Liquid crystal display device and motherboard
View Patent ↗A liquid crystal display device filled with a liquid crystal according to one drop filling prevents the liquid crystal from penetrating between a sealant and a TFT substrate or a counter substrate so as to reduce bonding strength in a seal part. The seal part has a wall spacer around the periphery of the sealant. In a terminal-side seal part, a second sealant is formed outside the wall spacer while a second wall spacer is formed outside the second sealant. Thus, the sealant, the wall spacer, and the sealant are sequentially formed in a plan view of a motherboard including liquid crystal display panels to be separated. This configuration can prevent the liquid crystal from penetrating into the seal part according to an internal pressure.
1. A liquid crystal display device comprising,
a TFT substrate having a display region and a terminal portion,
a counter substrate,
a sealant that bonds the TFT substrate and the counter substrate, and
a liquid crystal sealed inside the sealant,
wherein
the sealant has a first sealant and a second sealant, the first sealant is formed in a rectangular shape along the four sides of the counter substrate, the second sealant is formed outside the first sealant and formed only at one of the four sides that extends along the terminal portion,
a first wall spacer disposed between the first sealant and the second sealant at the one of the four sides, a second wall spacer disposed outside of the second sealant,
at least two rows of columnar spacers are formed in the first sealant, and
at least two rows of columnar spacers are formed in the second sealant.
2. The liquid crystal display device according to claim 1 , further comprising a plurality of scribing region spacers are formed between the end of the counter substrate and the second wall spacer.
3. The liquid crystal display device according to claim 1 , wherein the first wall spacer has an inner corner that is rounded with a curvature radius of at least 0.3 mm.
4. The liquid crystal display device according to claim 1 , wherein a color filter layer is formed between the counter substrate and each of the columnar spacers in the first sealant, and between the counter substrate and in the second sealant.
5. A display device comprises: a first substrate including a display region and a terminal region, a second substrate, and a sealant fixing the first substrate and the second substrate,
wherein

a first wall spacer disposed between the first sealant and the second sealant at the one of the four sides, a second wall spacer disposed outside of the second sealant,
at least two rows of columnar spacers are formed in the first sealant, and
at least two rows of columnar spacers are formed in the second sealant.
6. The liquid crystal display device according to claim 5 , further comprising a plurality of scribing region spacers are formed between the end of the second substrate and the second wall spacer in a plan view.
7. The liquid crystal display device according to claim 5 , wherein the first wall spacer has an inner corner that is rounded with a curvature radius of at least 0.3 mm.
8. The liquid crystal display device according to claim 5 , wherein a color filter layer is formed between the counter substrate and each of the columnar spacers in the first sealant, and between the counter substrate and in the second sealant.
