Abstract

The present invention relates to a cleaning composition for a liquid crystal alignment layer, a manufacturing method of a liquid crystal alignment layer using the same, and a liquid crystal display device including the liquid crystal alignment layer manufactured by the manufacturing method. More specifically, the present invention relates to a cleaning composition for a liquid crystal alignment layer that is capable of solving a non-uniformity problem of the liquid crystal alignment layer and effectively removing an ionic byproduct on a polymer surface to increase anisotropy of the liquid crystal alignment layer, by using a cleaning composition including a specific solvent in a cleaning process after a UV alignment process, and a manufacturing method of a liquid crystal alignment layer.
