Abstract: The present invention provides a liquid crystal display including a first substrate including a first alignment layer, gate lines, and data lines, a second substrate facing the first substrate and including a second alignment layer, and a liquid crystal layer disposed between the first substrate and the second substrate. A plurality of pixels are arranged in a matrix defined by the gate lines and the data lines, and alignment directions of the first alignment layer and the second alignment layer in a first pixel are different than alignment directions in a neighboring pixel.

Abstract: In an apparatus and a method for the printing of spacers in a pattern on substrates of display panels, a printer head includes a plurality of nozzle holes. Each printer head includes a nozzle group having a plurality of nozzle holes. A nozzle group may be selected by the conduction wirings on the vibration membrane and top plate sandwiching the piezoelectric actuators. To print complex patterns on the substrate a plurality of printer head sets, a plurality of printer heads in a line, can be arranged in various configurations.

Abstract: An ink pattern printing apparatus comprises a lower frame comprising a printing plate having at least one recess, and an upper frame comprising an ink supply device supplying ink onto the printing plate, a removing blade removing residual ink on an upper surface of the printing plate by releasing a pressurized gas through an exhaust port in the removing blade, and a transfer roller having a transfer sheet, wherein the transfer sheet receives transfer of ink from the at least one recess.

Abstract: An apparatus for printing spacers on a substrate of an LCD includes a spacer supply roller having a plurality of recesses formed in its exterior surface. A plurality of uniform volumes of an ink containing the spacers is loaded into the recesses and then transferred from the supply roller onto a transfer belt that is arranged to move tangentially with respect to the supply roller by means of a transfer roller and an auxiliary roller. The LCD substrate is then moved tangentially with respect to the moving transfer belt such that the ink volumes on the transfer belt are transferred onto the substrate at selected locations thereon. The continuously rotating components of the apparatus enable it to accommodate LCD panels of any size without the need for large spacer supply substrates and transfer rollers and prevent the inadvertent deposition of multiple layers of spacers on the substrate.

Abstract: An apparatus for manufacturing a display panel includes a printing plate having a plurality of recesses formed on its surface and a hole formed at at least one end thereof, a transfer roller for receiving ink injected in the recesses, a supporting plate for supporting a substrate thereon, wherein the ink from the transfer roller is transferred onto the substrate according to a rotation of the roller, and an ink re-using unit positioned in the hole. Productivity can be improved by reducing a fabrication cost by provision of the ink re-using unit to re-use ink.

Abstract: A print plate includes a surface including a central region and a peripheral region surrounding the central region, a panel print section and an alignment print section. The panel print section includes a plurality of panel spacer recesses disposed in the central region. The alignment print section includes a plurality of alignment spacer recesses disposed in the peripheral region. The alignment spacer recesses are spaced apart from each other.

Abstract: A spacer-printing apparatus includes a printing roller and a moving part. The printing roller has opposite edges connected by a curved surface and spacers are attached to the curved surface. The moving part is connected with the printing roller and respectively and alternately moves opposite edges up and down. The printing roller has a shape of a portion of cylinder, so that a radius is increased without the increase in volume and weight thereof.

Abstract: 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.

Abstract: 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.

Abstract: A liquid crystal display includes a first substrate having a display area and a peripheral area and including a plurality of pixels formed in the display area, a second substrate facing the first substrate, and a plurality of first groups of bead spacers and a plurality of second groups of bead spacers disposed between the first substrate and the second substrate. The first groups of bead spacers have a different size or different elasticity coefficient than the second groups of bead spacers, and include a plurality of bead spacers, respectively.
