PURPOSE: A getter composition and an organic electroluminescence (EL) display device including the same are provided to ensure high moisture absorption amount, rapid moisture absorption rate, and high dimension stability at high temperature and humidity and to control fluidity in dispensing and vacuum compressing processes. CONSTITUTION: A getter composition includes an absorbent and silicon copolymer with one or more functional groups selected from a group including a carboxylic acid group and a poly (alkylene oxide) group. The silicon copolymer has a structure represented by chemical formula 1. In chemical formula 1, R1-R6 are identical or different and are selected from hydrogen, a C1-C6 alkyl group, a C2-C6 alkenyl group, a C5-C10 cycloalkyl group, a C5-C10 cycloalkenyl group, a C6-C20 aryl group, and a C7-C20 aralkyl group; and R7-R10 are functional groups represented by chemical formula 2 or hydrogen, carboxylic acid groups, poly (alkylene oxide) groups, C1-C6 alkyl groups, C2-C6 alkenyl groups, C5-C10 cycloalkyl groups, C5-C10 cycloalkenyl groups, C6-C20 aryl groups, C7-C20 aralkyl groups, or C1-C6 alkyl groups, C2-C6 alkenyl groups, C5-C10 cycloalkyl groups, C5-C10 cycloalkenyl groups, C6-C20 aryl groups, or C7-C20 aralkyl groups with an either carboxylic acid group or a poly (alkylene oxide) group. |
