Claim:
1. An adhesive composition, comprising: an acrylic resin; an isocyanate cross-linking agent; and a carbodiimide cross-linking agent, wherein: the adhesive composition has a creeping distance of about 100 μm or less when the composition attached to a glass substrate with a bonding area of about 1.5 cm×1.5 cm is left at about 22° C. and about 50% RH for about 3 days and is subjected to a load of about 10 gf/mm the adhesive composition has a storage modulus of about 1×10 a difference between 180° peel strength (P1) and 180° Peel strength (P4) of the adhesive composition is 100 g/25 mm or less, where 180° peel strength (P1) is a 180° peel strength of a specimen measured by JIS 2107 between the adhesive composition and the glass substrate after the specimen was left for 1 day, and 180° peel strength (P4) is a 180° peel strength of the specimen measured by JIS 2107 between the adhesive composition and the glass substrate after the specimen was left for 4 days wherein the adhesive composition includes: 100 parts by weight of the acrylic resin; about 1 to about 30 parts by weight of the isocyanate cross-linking agent; about 0.001 to about 1 part by weight of the carbodiimide cross-linking agent; and wherein a weight ratio of the isocyanate cross-linking agent to the carbodiimide cross-linking agent is about 500:1 to about 3,000:1.
