Abstract
In a transfer printing apparatus having a blade-form ink extender and an ink extension member for extending an ink thereon in association with the ink extender, there is provided a means for removing an excess of the ink from the ink extender and/or and the ink extension member. The transfer printing apparatus is suitably used for forming a film of an organic polymer or an inorganic oxide in a process for production of a liquid crystal device.
Claims6
A process for producing a liquid crystal device comprising a liquid crystal disposed between a pair of substrates including a coated substrate, said process comprising the steps of:
- selecting a transfer printing apparatus comprising a projecting extender, an extension member for extending an ink thereon in association with the projecting extender, a printing plate for taking up the extended ink and transferring the ink to a substrate for providing said coated substrate, and removal means for removing an excess of the ink after extension from the projecting extender;
- applying a solution of an organic polymer or an inorganic oxide precursor onto the extension member;
- extending the applied solution on the extension member using the projecting extender;
- removing an excess of the extended solution after extension by the projecting extender;
- causing the printing plate to contact the extension member and transferring the extended solution to the substrate by the printing plate;
- and
- forming a film of the organic polymer or inorganic oxide on the substrate.
