Thin film transistors are formed on a lower substrate, and red, green, blue and transparent color filters are formed thereon. An organic insulating layer is formed on the color filters, and pixel electrodes are formed thereon. A black matrix and a common electrode are formed on an upper substrate facing the lower substrate.

Four color liquid crystal display and panel therefor

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.
