Abstract

PURPOSE:To permit easy automation of a process for producing a liquid crystal element by coating a liquid crystal by offset printing on a substrate on which electrodes are formed then superposing a substrate on which other electrodes are formed onto said substrate by pressing or the like thereby sealing the liquid crystal between two sheets of the substrate. CONSTITUTION:A liquid crystal 9 is coated by offset printing on a substrate 7 on which electrodes are formed then a substrate 11 on which other electrodes are formed is adhered onto said substrate and both substrates are adhered by a thermosetting press or the like to seal the liquid crystal 9. The need for an injecting hole is eliminated by packing the liquid crystal 9 between the substrates by printing in the above-mentioned way and therefore the need for a sealing part is eliminated. Generation of a projection owing to the sealing part is thus obviated and the mounting to electronic apparatus is improved. The automation of the packing stage and the stages before and after said stage is easy.

が極めて難しいという欠点を有していた。<Prior art> Conventionally, liquid crystal was filled into the inside of a liquid crystal cell by immersing an empty cell container into a liquid crystal dish containing liquid crystal material in a depressurized Pel jar, and then returning the inside of the Pel jar to atmospheric pressure. Liquid crystal was injected through an injection hole formed in the cell container using capillary action and a pressure difference between the inside and outside of the cell container. However, one or more conventional liquid crystal light and cloud methods have the drawback that automation of the manufacturing process is extremely difficult.

The numeral 53 on which the liquid crystal is transferred is a doctor bar, and the amount of liquid crystal transferred to the roll 2 is adjusted depending on the gap between the doctor bar 3 and the roll 2. Further, liquid crystal is transferred from the roll 2 to the roll 4. The roll 5 has a predetermined shape (
A relief plate 6 shaped in the shape of the area to be coated is applied, and liquid crystal is transferred from the roll 4 onto the relief plate 6.

。It should be noted that in printing the seal portion 8, the seal resin is printed in a predetermined pattern and then temporarily dried (at this time, the transition portion of the electrode is temporarily dried). Thereafter, the above-described liquid crystal transfer process is performed. After the transfer process of the liquid crystal, another electrode substrate is bonded to the electrode substrate while vacuum degassing is performed, and the electrode substrate is thermoset pressed and divided into individual cell units, thereby making it possible to create cells filled with a plurality of liquid crystals.
