Liquid crystal display including liquid crystal with different pretilt angles and method of manufacturing the same

摘要

A liquid crystal display includes first and second substrates, first and second alignment layers, and a liquid crystal layer between the alignment layers and including liquid crystal molecules. The liquid crystal molecules on a surface of the first alignment layer have a first pretilt angle in a direction which is vertical with respect to a horizontal plane surface parallel to the first substrate, and a first alignment angle in a direction which is horizontal with respect to a horizontal line parallel to the horizontal plane surface. The liquid crystal molecules on a surface of the second alignment layer have a second pretilt angle in the direction which is vertical with respect to the horizontal plane surface and different from the first pretilt angle, and a second alignment angle in the direction which is horizontal with respect to the horizontal line and different from the first alignment angle.
