Abstract
The present invention discloses a liquid crystal photo-alignment device. The liquid crystal photo-alignment device includes two parallel guide rails, a platform sandwiched between the two guide rails, a support assembly slidably mounted on the two guide rails, and a cleaning assembly mounted to the support assembly. The platform has a supporting surface for supporting a LCD panel. Each support assembly includes a supporting beam across the platform, two supporting arms extending from opposite ends of the supporting beam, and two sliders connected to the respective supporting arms. The sliders are slidably mounted in the guide rails. The cleaning assembly faces toward the platform and is configured to clean up foreign objects on the platform.
