Abstract:
The present invention provides a liquid crystal alignment film not only having an excellent alignment property and stability, but also having high film strength, and thus exhibiting excellent durability and a high residual image property, a method for preparing the same, and a liquid crystal display device using the same.

Claim (Index 9):
A method for preparing a liquid crystal alignment film including the steps of:\n 1) coating a liquid crystal aligning agent composition onto a substrate to form a coating film; 2) drying the coating film; 3) irradiating the coating film with light immediately after the drying step to perform alignment treatment; 4) subjecting the alignment-treated coating film to a low-temperature heat treatment at 200\u00b0 C. or lower; and 5) subjecting the heat-treated coating film to heat treatment at a higher temperature than that of the low-temperature heat treatment to cure it, wherein the liquid crystal aligning agent composition includes: i) a first polymer for a liquid crystal aligning agent including at least two repeating units selected from the group consisting of a repeating unit represented by Chemical Formula 21 below, a repeating unit represented by Chemical Formula 22 below, and a repeating unit represented by Chemical Formula 23 below, wherein the repeating unit represented by Chemical Formula 21 below is contained in an amount of 5 mol % to 74 mol % relative to the entire repeating units represented by Chemical Formulae 21 to 23 below; ii) a second polymer for a liquid crystal aligning agent including a repeating unit represented by Chemical Formula 24 below; and iii) a reactive mesogenic epoxy: wherein, in Chemical Formulae 21 to 24, R 22  and R 23  are each independently hydrogen or a C 1-10  alkyl, with the proviso that R 22  and R 23  are not all hydrogen, R 24  and R 25  are each independently hydrogen or a C 1-10  alkyl, and X 11  is a tetravalent organic group represented by Chemical Formula 25 below: wherein, in Chemical Formula 25, R 26  to R 29  are each independently hydrogen or a C 1-6  alkyl, X 12 , X 13 , and X 14  are each independently a tetravalent organic group derived from a hydrocarbon having 4 to 20 carbon atoms, or a tetravalent organic group in which at least one hydrogen in the tetravalent organic groups is substituted with a halogen or in which at least one \u2014CH 2 \u2014 is substituted with \u2014O\u2014, \u2014CO\u2014, \u2014S\u2014, \u2014SO\u2014, \u2014SO 2 \u2014, or \u2014CONH\u2014, so that it is not directly bonded to oxygen or sulfur atoms, and\n Y 11 , Y 12 , Y 13 , and Y 14  are each independently a divalent organic group represented by Chemical Formula 26 below: \n wherein, in Chemical Formula 26, R 30  and R 31  are each independently a halogen, a cyano, a C 1-10  alkyl, a C 2-10  alkenyl, a C 1-10  alkoxy, a C 1-10  fluoroalkyl, or a C 1-10  fluoroalkoxy, h and i are each independently an integer of 0 to 4, L 3  is a single bond, \u2014O\u2014, \u2014CO\u2014, \u2014S\u2014, \u2014SO 2 \u2014, \u2014C(CH 3 ) 2 \u2212 , \u2014C(CF 3 ) 2 \u2014, \u2014CONH\u2014, \u2014COO\u2014, \u2014(CH 2 ) z \u2014, \u2014O(CH 2 ) z O\u2014, \u2014O(CH 2 ) z \u2014, \u2014OCH 2 \u2014C(CH 3 ) 2 \u2014CH 2 O\u2014, \u2014COO\u2014(CH 2 ) z \u2014OCO\u2014, or \u2014OCO\u2014(CH 2 ) z \u2014COO\u2014, z is an integer of 1 to 10, and j is an integer of 0 to 3.
