Abstract
The present invention relates to a liquid crystal cell and a fabricating method thereof, more specifically, relates to a method for combining a pair of glass substrates and to a liquid crystal cell made thereby. A fabricating method according to the present invention includes steps of spreading spacers on an inner surface of a first transparent substrate provided with electrodes, and forming a seal member along the boundary edge of a second transparent substrate provided with electrodes after aligning the second substrate to be opposite to the first substrate. As the seal member is formed while the first and the second substrates are held under pressure, no special equipment is needed and no additional step of pressing is necessary after aligning the substrates. Furthermore, the seal member occupies smaller area in the alignment surfaces of the cell compared to a conventional art. As a reduced pressure is applied during aligning the substrates, adjusting the position of the substrates is easy and the movement of the substrates is reduced.
