Abstract
The invention is directed to a manufacturing method of a liquid crystal panel having first and second substrates, between which a liquid crystal layer and a seal wall surrounding the liquid crystal layer are sandwiched, includes the steps of (a) forming a seal wall precursor on the first substrate; (b) executing a preliminary hardening of the precursor; (c) laminating the first and second substrates with sandwiching the preliminarily and suitably hardened seal wall and a liquid crystal layer therebetween; and (d) executing, after step (c), a main hardening of the seal wall material. The invention is also directed to a manufacturing method of layered type liquid crystal panel including a plurality of such liquid crystal panels layered together.
Claims22
A manufacturing method of a liquid crystal panel having first and second substrates between which a liquid crystal layer and a seal wall surrounding the liquid crystal layer are sandwiched, said manufacturing method comprising the steps of:
- (a) forming a precursor of a material of the seal wall on the first substrate;
- (b) executing a preliminary hardening of the precursor formed on the first substrate;
- (c) laminating, after a time lapse from a completion of the step (b), the first and second substrates with sandwiching the preliminarily hardened seal wall therebetween, the time lapse being set so that the precursor of the material of the seal wall hardens to a hardness suitable for laminating the first and second substrates;
- and
- (d) executing, after the step (c), a main hardening of the material of the seal wall.
A manufacturing method of a plurality of liquid crystal panels each having first and second substrates between which a liquid crystal layer and a seal wall surrounding the liquid crystal layer are sandwiched, said manufacturing method comprising the steps of:
- (a) forming a precursor of a material of the seal wall on each of the first substrates;
- (b) simultaneously starting preliminary hardenings of the precursors formed on the first substrates;
- (c) sequentially completing the preliminary hardenings of the precursors formed on the first substrates;
- (d) laminating, in an order from the first substrate of which the preliminary hardening is lastly completed to the first substrate of which the preliminary hardening is firstly completed, the first substrates and the second substrates, respectively;
- and
- (e) executing, after the step (d), a main hardening of each of the materials of the seal walls.

- (b) starting preliminary hardenings of the precursors formed on the first substrates in a predetermined order among the first substrates;
- (c) completing, in the predetermined order, the preliminary hardenings of the precursors formed on the first substrates;
- (d) laminating, in the predetermined order, the first substrates and the second substrates with sandwiching the preliminarily hardened seal wall therebetween, respectively;
- and
- (e) executing, after the step (d), a main hardening of each of the materials of the seal walls.
