摘要： A method for manufacturing curved glass sheet includes the following steps: providing a mold which includes a first mold core and a second mold core corresponding to the first mold core; providing a raw glass sheet and placing the raw glass sheet on the second mold core; heating the first mold core to a first temperature, and heating the second mold core and the raw glass sheet to a second temperature which is equal to or lower than the glass transition temperature of the glass sheet but higher than the first temperature; closing the mold and hot pressing the first mold core on the glass sheet; opening the mold, and cooling the glass sheet to obtain the curved glass sheet. An annealing step can also be provided to the curved glass sheet. A mold for manufacturing the curved glass sheet is also provided.
