Abstract:
1. A method for manufacturing an LCD device comprising: (a) positioning a cliché plate and a first substrate on a moving rail; (b) first, rolling a printing roller having a pattern material on the cliché plate wherein a portion of the pattern material is transcribed on the cliché plate and a portion of the pattern material remains on the printing roller; then, rolling the printing roller having the remaining portion of the pattern material on the first substrate wherein the remaining portion of the pattern material is transcribed on the first substrate; (c) cleaning the cliché plate after transcribing the remaining portion of the pattern material on the first substrate; (d) forming a light-shielding layer on the first substrate; (e) forming a color filter layer on the first substrate including the light-shielding layer; (f) preparing a second substrate; and (g) forming a liquid crystal layer between the first and second substrates, wherein at least one of the processes of forming the light-shielding layer on the first substrate, and forming the color filter layer on the first substrate including the light-shielding layer is performed using steps (a)-(c), wherein the step of the cleaning the cliché plate is performed by using a cleaning unit including a cleaning part that moves to the cliché plate for cleaning and a container for accommodating a new cliché plate and the cleaned cliché plate.
