イス呼ぶ)である。[Technical Disadvantages and Problems of the Invention] Recently, the application of optical anisotropy of liquid crystals to display devices has been progressing in various fields. The most commonly used display method is one that utilizes the dynamic scattering phenomenon in which a nematic liquid crystal compound with angular dielectric anisotropy scatters light when an electric field is applied (hereinafter referred to as DS type device). (hereinafter referred to as the FE type vise), which is used for display by avoiding changes in optical rotation by orienting a nematic liquid crystal compound with positive anisotropy.
DS型デバイスでは、液晶の初期配向の均一性が動作原
理上必ずしも必要ではないが、FE型型式バイスは動作
原理が電場により液晶の初期配向を制御もしくは再配列

ため、液晶の初期配向の均一性が特に重要である。 然

ているが、この方法では部分的に液晶分子の配向が異な
り、配向の均一性は十分で4丁り、また配向が短時間の
うちに失われてしまう欠点がある。In the DS type device, uniformity of the initial alignment of the liquid crystal is not necessarily required for the operating principle, but in the FE type device, the operating principle is to control or rearrange the initial alignment of the liquid crystal using an electric field, and the optical principle at that time is used. The uniformity of the initial alignment of the liquid crystal is particularly important because changes in the liquid crystal are utilized. Conventionally, a method of rubbing the electrode substrate in one direction with cloth or the like has been known as a means of obtaining uniformity of the initial alignment of liquid crystal, but with this method, the alignment of liquid crystal molecules is partially different, and the alignment Although the uniformity of the film is sufficient, it has the disadvantage that the orientation is lost within a short period of time.

きないという欠点がある。In order to overcome the above drawbacks, a method has been used in which the electric TFI substrate is rubbed in one direction using a certain type of surfactant, but this method improves the uniformity of orientation to some extent. Another problem is that the surfactant has no heat resistance, and the surfactant causes deterioration of the liquid crystal.Furthermore, if an electric field is continued to be applied, the surfactant will decompose and change in quality due to the electric field, and the orientation will be destroyed. It has the disadvantage of being Furthermore, a method is used in which an electrode substrate coated with a conventional integrated polyimide resin is rubbed in one direction, but this method has excellent alignment effects and heat resistance for liquid crystals, but the curing and condensation temperature of the polyimide resin is Due to its high cost, it has the disadvantage that it cannot be coated on flexible electrode substrates (for example, films made of polyester stellate, etc.).

性が良くなかった。Comparative Example 2 A display device was created in the same manner as in Comparative Example 1 after creating the neri glass in which the orientation treatment was performed by directly rubbing the neriglass surface in one direction with a cloth without using the orientation treatment agent in comparative example 1. This display device had uneven alignment of brightness and darkness in the display area when an electric field was applied, and the alignment began to break down after 3 hours at 50°C, and completely broke down after 2 days, resulting in poor durability and heat resistance.
