Latest Patents

Miyata's latest patents include a method of manufacturing a liquid crystal display device. In one embodiment, he prepares a first substrate with multiple array regions. A seal material is formed in each of these array regions, while a peripheral seal material is arranged outside the array regions extending in a first direction. This peripheral seal material features an exhaust opening that is positioned at a portion extending in a second direction. Additionally, a dummy seal material is created between the peripheral seal material and the seal material in the array region. A second substrate is then placed on the surface of the first substrate within a jig. The jig is decompressed, and the atmosphere between the first and second substrates is exhausted while applying pressure to both substrates. Finally, the first and second substrates are bonded by curing the seal material, peripheral seal material, and dummy seal material.

Another patent by Miyata also pertains to the manufacturing of liquid crystal display devices. In this embodiment, he prepares a first substrate that includes first and second array regions, each containing active areas. A peripheral seal material with an air intake opening is arranged outside these array regions. The second substrate is then placed on the surface of the first substrate, where the seal materials are formed in a vacuum chamber. The atmosphere is introduced into the vacuum chamber, creating a pressure difference that facilitates the attachment of the substrates.
