Disclosed are a liquid crystal composition and a liquid crystal display using the same. The liquid crystal composition includes a polar compound and a low-viscosity compound. The liquid crystal display includes first and second substrates that face each other, and first and second electrodes disposed on the first and second substrates, respectively. A liquid crystal layer including the liquid crystal composition is disposed between the first and second substrates.
摘要:
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.
摘要:
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.

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.
摘要:
An apparatus for printing bead spacers at selected locations on an LCD substrate includes a cylindrical transfer roller and a printing plate having a plurality of semispherical recesses respectively located at positions corresponding to the selected locations of the spacers on the LCD substrate. A volume of an ink containing the spacers is loaded into each of the recesses, and the substrate is translated tangentially relative to the rotating transfer roller such that the volumes of ink are transferred onto the roller. A support plate having the LCD substrate mounted thereon is then translated tangentially relative to the roller such that the volumes of ink on the roller are transferred onto the surface of the LCD substrate at the selected locations. The apparatus enables the spacers to be printed onto the LCD substrate accurately and inexpensively, and prevents the spacers from being inadvertently printed in double layers.
