Development of Novel Alignment Method

From the early stages of LCD production in the 70s, only the rubbing method has been adopted for alignment technologies. The rubbing method is a simple, convenient, and low-cost, and it is considered unlikely that the rubbing method 

Especially in the early stages of TFT device production, the destruction of thin film transistors by static electricity was a serious problem because the reliability of the transistors was quite low. This problem has been dealt with gradually. However, the occurrence of fibre dust has been a continuing problem, and has imposed restrictions on production lines. Moreover, the mechanism of the liquid crystalline alignment is not clearly understood.
