Patent ID: 7388645

Claim:
A method of pressure-sealing a ferroelectric liquid crystal display, comprising: injecting a ferroelectric liquid crystal into a liquid crystal display panel; pressurizing the liquid crystal display panel into which the ferroelectric liquid crystal has been injected; applying an electric field to the liquid crystal display panel simultaneously with the pressurization of the liquid crystal display panel; and performing a temperature treatment of the liquid crystal display panel simultaneously with the pressurization of the liquid crystal display panel, wherein pressurizing, applying an electric field and performing a temperature treatment are performed using a pressure sealing apparatus, the pressure sealing apparatus comprises; an upper pressurizing plate, a plurality of voltage-applying bars formed at an edge of the upper pressurizing plate, a lower plate, and a heat coil formed at the interior of the upper pressurizing plate and the lower plate, wherein the liquid crystal display panel is disposed between the upper pressurizing plate and the lower plate.
