ABSTRACT:
A method of producing a liquid crystal display unit, in which a flat substrate and a flexible film substrate are bonded to each other through a gap, and in which a liquid crystal is charged and sealed in a closed space of the gap enclosed by a frame-like sealing agent. The method comprises steps of: providing spacers on a bonding surface of the flat substrate in advance to thereby form the gap and transferring the sealing agent to a bonding surface of either one of the flat substrate and the film substrate; making the flat substrate enter into an insertion gap between a pair of pressure rollers and making the film substrate enter into the insertion gap at an inclined angle with respect to the flat substrate to thereby carry the flat substrate and the film substrate under pressure; at the same time, ejecting a required amount of the liquid crystal into a space between the flat substrate and the film substrate in accordance with the substrate-carrying velocity, the space being narrowed gradually toward the insertion gap; and squeezing the liquid crystal ejected into between the flat substrate and the film substrate in a direction reverse to the substrate-carrying direction to thereby fill the gap between the flat substrate and the film substrate with the liquid crystal.
