LIQUID CRYSTAL DISPLAY DEVICE, METHOD OF MANUFACTURING THE SAME, AND ALIGNMENT LAYER COMPOSITION
Abstract:
A liquid crystal display includes: a lower substrate; an upper substrate facing the lower substrate; an alignment layer on the lower substrate and the upper substrate; and a liquid crystal layer between the lower substrate and the upper substrate. The alignment layer includes two monomers including polyimide and a reactive mesogen, and an alignment solvent. The alignment solvent includes a first solvent configured to increase solubility of a polymer, a second solvent configured to increase spreadability of the alignment solvent, and a third solvent configured to decrease vapor pressure of the alignment solvent. A total content of the first solvent and the second solvent is from about 70 weight percent to about 95 weight percent based on a total weight of the alignment solvent. The alignment solvent has the vapor pressure at 90° C. from about 10 mm Hg to about 20 mm Hg.
