PURPOSE:To form an oriented film having good film quality and uniform film thickness by applying a soln. prepd. by mixing the materials for the oriented film and a solvent on a glass substrate and removing the soln. mixture of the prescribed regions on the substrate by using a sponge-like member impregnated with the same solvent, then forming the oriented film. CONSTITUTION:The soln. 23 prepd. by mixing the materials for the oriented film and the solvent is applied by a spin coating method on the glass substrate 20 on which transparent electrodes 21 are formed. After the soln. mixture 23 of the prescribed regions on the glass substrate 20 is removed by using the sponge-like member 24 impregnated with the same solvent as the above- mentioned solvent, the soln. mixture 23 remaining on the glass substrate 20 is cured to form the oriented film. The soln. mixture 23 is easily dissolved by discharging the solvent contained in the sponge-like member 24 in such a manner and the simultaneously dissolved soln. mixture 23 is immediately absorbed by the sponge-like member 24; therefore, the soln. mixture 23 of the parts wiped with the sponge-like member 24 is cleanly removed. The oriented film having the good quality is obtd. in this way and the electrical characteristics of the liquid crystal display device are improved. |
