Abstract

A syringe for fabricating a liquid crystal display panel is provided. The syringe includes a body, a plurality of nozzles, and a connection portion. The body portion has a dispensing material contained therein. The plurality of nozzles supply the dispensing material received from the body portion to a substrate of the liquid crystal display panel. The connection portion are provided on a bottom surface of the connection portion and couples the nozzles with the body portion.

Claims (11)

1. A method of fabricating a liquid crystal display panel, comprising:

providing a thin film transistor array substrate having N×M liquid crystal display panels;

providing a color filter substrate having N×M liquid crystal display panels;

providing N syringes to align each nozzle of the syringes with a dispensing position of each liquid crystal panel, N syringes being arranged to a support in a longitudinal direction of the support, each syringe including a body portion extending in a downward direction from the support to contain dispensing material therein, a connection portion connected to each body, and M nozzles disposed at a bottom surface of each connection portion and spaced in a longitudinal direction of the connection portion so that M nozzles are connected to each body through the connection portion to supply the dispensing material received from the body portion to a substrate of the liquid crystal display panel, the longitudinal direction of the connection portion being perpendicular to the longitudinal direction of the support so that M nozzles attached to the same connection portion are spaced in a direction that is perpendicular to the spacing direction between adjacent N syringes;

dispensing a material through the plurality of nozzles onto a plurality of the liquid crystal display panels of at least one of the thin film transistor array substrate and the color filter substrate; and

joining together the thin film transistor array substrate and the color filter substrate,

wherein one nozzle dispenses the material onto one liquid crystal panel so that one syringe dispenses the material onto a plurality of liquid crystal panel at the same time,

wherein each nozzle is moving at the connection portion in at least one direction to align the nozzles of each syringe to the dispensing position in accordance with the size of the liquid crystal display panel,

wherein N syringes are supported by one support so that N×M nozzles are simultaneously aligned with the dispensing position by moving the support,

wherein the interval between the neighboring nozzles at one syringe is substantially same as that between the neighboring liquid crystal display panels.

2. The method according to claim 1 , wherein a number of syringes are provided corresponding to a number of columns of image display portions formed on the substrate and wherein a number of nozzles are provided on each syringe corresponding to a number of rows of image display portions formed on the substrate.
