The present invention relates to a Gamma-voltage generation device and a Liquid Crystal Display (LCD) device, wherein the Gamma-voltage generation device comprises: a voltage series generation unit for generating a plurality of groups of voltage series; and a multi-path selection unit for selecting one voltage value from each group of voltage series, respectively, according to a voltage selection signal and outputting the same to generate a needed Gamma-voltage series. The LCD device comprises a display panel, a row driver and a column driver, a timing controller, an image analyzing and processing unit, and a Gamma-voltage series generation device. The present invention achieves dynamic Gamma-voltage generation by choosing among a plurality of groups of voltages to output the needed Gamma-voltage series. Further, the plurality of groups of Gamma-voltage series could be obtained with resistor networks and such devices in the existing art as DAC and the like are unnecessary, thereby the response rate is improved and the cost is reduced.
