An apparatus for printing bead spacers on a substrate of an LCD panel includes a head unit for spraying a plurality of bead spacer groups on the substrate, a transfer unit for transferring the head unit, and a supply unit for supplying the bead spacers to the head unit. Each of the bead spacer groups includes a plurality of bead spacers, and the sizes of the respective spacers of at least two of the spacer groups are different from each other. The invention enables a cell gap of a substantially uniform thickness to be created and maintained in the panel, prevents the occurrence of smear failures in the panel, and increases the allowable tolerance in the amount of liquid crystal material needed to fill the panel correctly.

A spacer ink printing apparatus for printing spacers on an LCD substrate includes a main body, a pressing roller and a spacer ink removing portion. The apparatus may further include a spacer ink guiding portion and/or a spacer ink spreading portion. The pressing roller is combined with the main body and rotates so as to press a spacer ink sprayed onto a printing plate into each of a plurality of receiving recesses of the printing plate. The spacer ink removing portion is combined with the main body and serves to remove any excess spacer ink from the printing plate, thereby reducing wasted spacer ink and decreasing the manufacturing cost of LCDs produced with the apparatus.

A display panel includes a first substrate, a second substrate, a liquid crystal layer, a seal line and an outer spacer. The first substrate includes a display area on which a plurality of thin film transistors are formed, and a peripheral area surrounding the display area. The second substrate is opposite to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate. The seal line is formed between the first substrate and the second substrate in the peripheral area to confine the liquid crystal between the first and second substrates. The outer spacers are disposed in the peripheral area, and inwardly spaced apart from the seal line by a separation distance thereby preventing liquid crystal from being polluted by particles of an uncured seal line during manufacturing.

Apparatus and methods for printing spacers on LCD substrates include a printing roller and a planarizing unit. The printing roller picks up a plurality of spacer ink dots, each containing a plurality of minute, rigid, spherical spacers, onto an outer surface thereof and prints them on an LCD substrate at selected locations thereon. The planarizing unit is spaced apart from the outer surface of the printing roller and operates to planarize the spacers such that the spacers are arranged in a single layer having a uniform height substantially equal to the diameter of the spacers. The planarizing unit thereby prevents the spacers from being printed on the substrate in multiple layers such that the cell gap between the substrates of the LCD does not vary, but is uniform in height, thereby improving the quality of the image produced by the display.
