Abstract
An apparatus for inspecting an alignment film and a method for fabricating a liquid crystal display device using the same are disclosed. By changing a spraying structure of a steam inspecting unit to check whether an alignment film is defective or not, a water splash phenomenon can be prevented and spraying can be performed uniformly on a large-scale glass. The apparatus for inspecting an alignment film comprises a first steam generating unit for generating first steam; a second steam generating unit for generating second steam by using the first steam as a heat source; and a steam spraying unit for spraying the second steam onto a substrate of a substrate to inspect an alignment film formed on the substrate.
