■Overview
Liquid crystal displays (LCD) are used for mobile phones, TVs, PC monitors, PDAs, etc. SEIMI CHEMICAL started to produce liquid crystal mixtures in 1978 for instrument panels in auto mobiles. Many unique liquid crystal compounds have developed such as SSC and chiral additives.
We are investigating new liquid crystal compounds for TFT applications. |
