Patent JP-H0470813-A (JP)
Title: Liquid crystal element and its manufacture
Inventor: YAMAZOE HIROSHI
IPC: G02F1/1337
Filed: 1990-07-12
Abstract: PURPOSE:To enable the high-pretilt and stable orientation of liquid crystal molecules by forming layers of solid organic molecules and vertical orienting agent layers on the main surfaces of a 1st and a 2nd substrate and inserting liquid crystal between both the substrates. CONSTITUTION:The layers 5 and 6 consisting of the arrayed solid organic molecules and the vertical orienting agent layers 7 and 8 are formed in this order on the main surfaces of the 1st substrate 1 or 2nd substrate 2 and the liquid crystal composition 9 is inserted between both the substrates to form the liquid crystal element. When there are the organic molecule layers 5 and 6 right below the vertical orienting agent layers 7 and 8, a restricting force to the vertically oriented liquid crystal molecules is affected by the array below them to obtain slanting orientation. For example, a polyimide layer is formed on a substrate and rubbed. Then a vertical orienting agent is applied. Consequently, the pretilt angle of the liquid crystal molecules which is about 10 - 89.8 deg. is obtained with good reproducibility. Consequently, no vacuum device is required and the cost is therefore reduced as compared with an orienting method using oblique vapor deposition.
