Abstract
A patterning method and a method for manufacturing an LCD device using the same are disclosed. The patterning method includes preparing a printing plate having concave and convex portions; coating a pattern material in the concave portion of the printing plate; rolling a printing roller on the printing plate to print the pattern material of the concave portion on the printing roller; and rolling the printing roller on a substrate to print the pattern material of the printing roller on the substrate.
Claims6
A method for manufacturing an LCD device comprising:
- preparing a first substrate and a second substrate;
- forming a pattern on the first substrate;
- and
- forming a liquid crystal layer between the first and second substrates,
- wherein forming a pattern on the first substrate comprises:
- preparing a printing plate having recesses and lands;
- dropping a pattern material into the recesses of the printing plate using at least one precision nozzle to form the pattern material in the recesses of the printing plate,
- stopping said dropping a pattern material into the recesses before a height of the pattern material formed in each recess reaches one-half a depth of the recess in order to prevent coating of lands of the printing plate,
- rolling a printing roller on the printing plate to print the pattern material in a recess of the printing plate onto the printing roller, wherein the printing roller comprises a blanket of Si-based resin, having elasticity, adhered to a surface thereof;
- and
- rolling the printing roller on the first substrate to print the pattern material on the printing roller onto the first substrate.
