The invention relates to an optical adhesive composition for a vehicle head-up display device. The present invention relates to an optical adhesive composition, and more particularly, to an optical adhesive composition having excellent durability for improving environmental reliability such as high-temperature stability, high-temperature/high-humidity stability, light resistance, and the like by using a siloxane urethane acrylate oligomer having a hard segment and a siloxane structure into which an inorganic structure is introduced, an optical transparent adhesive film using the same, and a display device using the same. 本发明涉及车辆抬头显示装置用光学粘合组合物，尤其涉及通过采用导入无机结构的硅氧烷结构及硬链段的硅氧烷氨基甲酸乙酯丙烯酸酯低聚物来提高高温稳定性、高温/高湿稳定性、耐光性等环境可靠性的耐久性优秀的光学粘合组合物及利用其的光学透明粘合膜和其显示装置。
