Abstract

PURPOSE: To cheaply manufacture a high-quality plastic liquid crystal display panel having no liquid crystal injection hole by holding a liquid crystal between two transparent plastic substrates with a specified sealing agent coated and dried and heating them.
CONSTITUTION: A thermoplastic linear high-molecular substance (a) such as nylon and liquid epoxy resin (b) having a relatively low MW of about 300W400 and inducing cross linkage with nylon by heating are blended in a ratio of about 2.5W 3:1. About 10W20wt% of this blend is dissolved in a solvent such as 1,1,1,3,3,3- hexafluoro-2-propanol which dissolves the components (a), (b) and a plastic substrate such as a polyester substrate. The resulting sealing agent is coated onto the sealing positions of plastic substrates and dried at about 40W80°C for about 30W 60min. The substrates are then superposed with a liquid crystal in-between and pressure-bonded at about 120W150°C for about 2W3sec while pressing slightly to form a display panel.
