Liquid crystal display

A liquid crystal display, comprising:

• a liquid crystal panel that includes vertical alignment liquid crystals encapsulated between a first substrate and a second substrate;
• a first compensation layer stacked on one side of the first substrate;
• a first polarizing layer stacked on one side of the first compensation layer;
• a second compensation layer stacked on one side of the second substrate;
• and
• a second polarizing layer stacked on one side of the second compensation layer,
• wherein the first compensation layer includes a polyimide copolymer represented by Formula 1:
• wherein, in Formula 1,
• each R is independently a substituted or unsubstituted C1-C6 alkyl group or a substituted or unsubstituted C6-C12 aryl group;
• each Ar is independently a substituted or unsubstituted C6-C12 aryl group;
• and
• M and N are each independently an integer from 2 to 8.
