Abstract: 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.

Abstract translation: 根据一滴式填充液体填充液晶的液晶显示装置防止液晶渗透到密封剂与TFT基板或对置基板之间，从而降低密封部中的接合强度。 密封部分具有围绕密封剂周边的壁间隔件。 在端子侧密封部中，在壁间隔件的外侧形成有第二密封剂，而在第二密封剂的外侧形成有第二壁隔离物。 因此，密封剂，壁间隔件和密封剂依次形成在包括要分离的液晶显示面板的母板的平面图中。 这种结构可以防止液晶根据内部压力渗入密封部。
