Abstract
A process for producing a liquid crystal display having less alignment defects, which seldom causes aligning disorder at the boundary where ferroelectric liquid crystals allowed to flow are brought into contact with each other when the ferroelectric liquid crystals are coated on the substrate flow. The process includes a first alignment layer formation step and a liquid crystal coating step. The liquid crystal coating step is a step of linearly coating the ferroelectric liquid crystals on a first alignment layer of a liquid crystal side substrate in a direction substantially perpendicular or substantially parallel to the alignment treatment direction conducted in the first alignment layer formation step.
Claims9
A process for producing a liquid crystal display, the process comprising:
- a liquid crystal side substrate preparation step including a first alignment layer formation step of forming a first alignment layer-formation layer on a first substrate on which a first electrode layer is formed and subjecting the first alignment layer-formation layer to alignment treatment to form a first alignment layer, to prepare a liquid crystal side substrate in which the first electrode layer and the first alignment layer are laminated in this order on the first substrate;
- a counter substrate preparation step including a second alignment layer formation step of forming a second alignment layer-formation layer on a second substrate on which a second electrode layer is formed and subjecting the second alignment layer-formation layer to alignment treatment to form a second alignment layer, to prepare a counter substrate in which the second electrode layer and the second alignment layer are laminated in this order on the second substrate;
- a liquid crystal coating step of linearly coating a ferroelectric liquid crystal to a surface of the first alignment layer of the liquid crystal side substrate in a direction substantially perpendicular or substantially parallel to a direction of the alignment treatment conducted in the first alignment layer formation step;
- and
- a substrate attaching step of providing the liquid crystal side substrate to which the ferroelectric liquid crystal is coated and the counter substrate to face each other such that the direction of the alignment treatment conducted in the first alignment layer formation step and a direction of the alignment treatment conducted in the second alignment layer formation step are substantially parallel to each other, and attaching the both substrates.
