Liquid optical material, display panel comprising same and laminating method

The method comprises the following steps: (1) printing a liquid optical material on the surface of a touch display module in a 3D printing manner, and curing to form an enclosed frame retaining wall; the viscosity of the liquid optical material is greater than or equal to 10000 cp, and the thixotropic index is greater than or equal to 2.0; (2) liquid optical transparent resin is coated in the space defined by the frame retaining wall, leveling and curing are carried out, and a full-lamination optical adhesive layer comprising the frame retaining wall and a liquid optical adhesive layer filled in the frame retaining wall is formed; and (3) laminating the cover plate on the touch display module with the full-lamination optical adhesive layer. According to the liquid optical material and the preparation method thereof, the viscosity, the thixotropic index, the surface tension and the like are adjusted by adding the auxiliaries into the OCR, so that the obtained liquid optical material is high in shape retention,
