A double-sided optically clear adhesive is provided. The double-sided optically clear adhesive includes a first adhesive layer and a second adhesive layer. The first adhesive layer includes a first resin and a first thermal-crosslinking agent. The first resin includes a hydroxyl group. The first thermal-crosslinking agent includes a first group. The second adhesive layer includes a second resin and a second thermal-crosslinking agent. The second resin includes a hydroxyl group. The second thermal-crosslinking agent includes a second group. The ratio of the equivalent number of the first group of the first thermal-crosslinking agent to the equivalent number of the hydroxyl group of the first resin is represented by r. The ratio of the equivalent number of the second group of the second thermal-crosslinking agent to the equivalent number of the hydroxyl group of the second resin is represented by r, wherein r<r≤0.8 and r−r≥0.025.
