Gamma voltage generating apparatus for display device

In an apparatus for generating a gamma voltage to enhance a display quality and a display device having the apparatus, the apparatus of the display device having a display panel and a plurality of driving chips mounted on the display panel, each of the driving chips having a data driving part for outputting a data signal, includes a plurality of gamma resistors, output terminals and a stabilizing circuit part. The gamma resistors are serially coupled between a power terminal and a ground terminal. The output terminals are directly connected to a data driving part for outputting distributed gamma voltages. The stabilizing circuit part is electrically connected to the output terminals and is mounted on a printed circuit board disposed on a side of the display panel for stabilizing the gamma voltages. Therefore, an output deviation among the driving chips is removed, so that the display quality can be enhanced.
