Inkjet technology was used in a mass production process to form an alignment layer on high‐temperature polysilicon TFT liquid crystal panels used in LCD projectors. This is the first‐ever inkjet process for forming alignment layers in an LCD manufacturing process. Surface treatment, inkjet ejection, and post‐print drying processes were integrated, and process conditions and printing materials were optimized, thereby sharply improving display quality while reducing process environmental impact.
