The present invention relates to an acrylic pressure sensitive adhesive composition containing ester plasticizer having at least one of ether linkages in the molecule represented by formula 1, alkali metallic salt and quaternary ammonium salt together and polarizer and LCD using the same. The acrylic pressure sensitive adhesive composition of the present invention for polarizer has improved antistatic property, owing to the synergy effect of ester plasticizer having one or more ether linkages, alkali metallic salt and quaternary ammonium salt, in addition to the excellent adhesive force and durability. In particular, the acrylic pressure sensitive adhesive composition provided by the present invention shows excellent durability and improved antistatic property by adding quaternary ammonium salt containing weakly coordinated anions.
