The invention belongs to the field of optical cement, in particular to OCA optical cement and an OCA optical cement film. The OCA optical cement comprises, by weight, 10-40 parts of saturated polyacrylate with cross-linkable groups, 20-40 parts of oligomers with unsaturated bonds, 20-40 parts of diluent, 0.5-5 parts of photoinitiator and 0.1-2 parts of cross-linking agent. According to the OCA optical cement and the OCA optical cement film, components of the optical cement is subjected to optimization selection, and the OCA optical cement with excellent performance is obtained; the OCA optical cement is excellent in coating wettability, and shrinkage holes cannot exist on a base material in coating; the OCA optical cement film prepared from the optical cement has higher viscidity, residual gum does not easily exist when the optical cement film is attached to a display material, and the cement film has better stripping performance. The invention further provides the OCA optical cement film, the OCA optical cement film is formed after coating and solidifying of the OCA optical cement and has higher viscidity and better stripping performance.
