Ceramic laminate sheet with flexibility and preparation method thereof

Disclosed is a ceramic laminate sheet comprising a ceramic sheet having a plurality of cracks and a polymer resin layer disposed on one side or both sides of the ceramic sheet, wherein the plurality of cracks pass through the ceramic sheet from one side to the other side thereof, the cracks divide the ceramic sheet into a plurality of pieces, grooves for formation of the cracks are not provided in one side and the other side of the ceramic sheet. Since the ceramic laminate sheet of the present invention does not have a groove for crack formation, it is possible to significantly reduce the process time and cost and also have ceramic material properties equal to or more favorable than conventional ceramic sheets. The ceramic laminate sheet has excellent flexibility in any direction even without the formation of grooves and the material properties are not deteriorated even with a deforming force or impact applied thereto. The ceramic laminate sheet of the present invention can be easily attached to curved or fle
