摘要： In a coating method for forming a film of a coating material on a substrate by supplying the coating material from a coating unit to the substrate held by a stage while the coating unit is moved relative to the stage, the stage includes a substrate-holding section and a peripheral section which has a surface higher than that of the substrate-holding section. The coating method includes the steps of mounting the substrate on the substrate-holding section of the stage; forming the film of the coating material so that the coating covers the substrate and extends to the peripheral section; and removing the coating material remaining in the peripheral section by a coating material removing unit after the substrate provided with the film is dismounted from the stage.

摘要： A liquid crystal device is constituted by a pair of oppositely disposed substrates having opposing inner surfaces and opposing electrodes thereon, and a chiral smectic liquid crystal disposed between the opposing electrodes. The liquid crystal device has an effective optical modulation region (2) and a peripheral region (3) outside the effective optical modulation region. In the device, liquid crystal molecules in the peripheral region have a pretilt angle (α₂) which is larger than a pretilt angle (α₁) of liquid crystal molecules in the effective optical modulation region. As a result, a local pressure irregularity or a cell thickness change caused by a liquid crystal molecular movement along an extension of the device is effectively suppressed.
