IPC: G02F1/1341
Filed: 2000-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid crystal device, preventing visible defect due to residual air bubbles in a liquid crystal layer, without producing variation of components in a smectic liquid crystal under heating. SOLUTION: The smectic liquid crystal is applied around a liquid crystal injection port of a cell. Subsequently, the atmosphere surrounding the cell is evacuated, and simultaneously the liquid crystal is heated within a range not to bring about phase transition of the liquid crystal to an isotropic or nematic phase. Next, the vacuum level is lowered, until the phase transition of the liquid crystal to the isotropic or nematic phase is brought about, so as to realize phase transition of the liquid crystal to the isotropic or nematic phase. The liquid crystal injection port is obstructed by the liquid crystal having increased fluidity caused by the phase transition. Next, the atmosphere surrounding the cell is again evacuated for evacuating the inside of the cell through an evacuation port and the evacuation port is sealed, while maintaining the evacuated state inside the cell.  Subsequently the liquid crystal, obstructing the liquid crystal injection port, is injected into the inside of the cell by releasing the evacuated state of the atmosphere surrounding the cell. As the last step, the liquid crystal injection port is sealed.
