A gamma reference voltage generating device, a method for generating gamma reference voltages, and a gray level voltage generating device are provided. The gray level voltage generating device includes a selection unit and a gray level voltage generator. The selection unit is adapted for receiving M first gamma reference voltages, and selecting N second gamma reference voltages from the M first gamma reference voltages and outputting the N second gamma reference voltages, wherein M and N are positive integers, and M>N. The gray level voltage generator is coupled to the selection unit, for generating a plurality of gray level voltages according to the N second gamma reference voltages. The gamma curve can be adaptively adjusted by using the present invention so as to improve the display quality.
