Method of manufacturing liquid crystal element comprising maintaining
pressure by controlling vacuum in the cell gap during hardening of
sealant
Abstract:
A pair of electrode substrates are combined with a sealing material and spacers therebetween. A cell gap of a liquid crystal display element is controlled by maintaining the pressure in the space between the pair of electrode substrates at a predetermined pressure for a period of time as part of an evacuation process for the pair of electrode substrates, and pressing the pair of electrode substrates with atmospheric pressure. This prevents a sealing edge from becoming irregular due to bubbling of the sealing material, thereby providing the liquid crystal display element thus obtained with good linearity in the sealing edge. Moreover, since movement of the spacers near an exhaust port is prevented, irregular display coloring is eliminated, which enables the liquid crystal display element to have good display characteristics. Furthermore, since the sealing edge does not become irregular, the liquid crystal display element has excellent uniformity in the cell gap.
