PROBLEM TO BE SOLVED: To improve alignment processing speed, embody stable liquid crystal molecule alignment and obtain high productivity by forming a light reaction type alignment layer on one side of a substrate and subjecting the reaction type alignment layer to optical irradiation, while heating the layer, thereby imparting liquid crystal alignment controllability to the optical reaction type alignment layer. SOLUTION: A heating stage 18 forms a space part 30, bored in the lower side of a substrate 17 loading section. Hot wind 21 formed by a hot wind heater 19, disposed in the space part 30, is introduced into the space part from the inside wall surfaces on four sides, with which the substrate 17 provided with the alignment layer is heated. As a result, UV irradiation light 13 enters the inside of the bored space part 30, and therefore, the reflection at the rear surface of the substrate 17 is eliminated. A UV reaction type alignment layer is formed as the light reaction type alignment layer and is subjected to the irradiation with UV rays, while the layer is preferably heated to 45 to 75 deg.C. A polyimide type aligning agent, etc., may be used as the material of the UV reaction type alignment layer. |
