Disclosed is an LCD having an adaptive luminance intensifying function and driving method thereof. A timing controller checks features of externally provided image data, and when they are found to be moving pictures, it determines a luminance level required from the image data and outputs a luminance level control signal, and when they are found to be still images, outputs a predetermined luminance signal. A backlight driver outputs a high-potential backlight driving voltage to the backlight unit when a luminance control signal of high-luminance level driving is provided by the timing controller, and outputs a constant level luminance signal when a constant luminance signal is input. As a result, by selecting a plurality of portions of the displayed screen and tracking and monitoring the changes of the image data, features of the images are defined and application conditions of the luminance intensifying function are determined to control the luminance level of the backlight and outputs of gamma voltage levels. Accordingly, the contrast of a display screen is improved and the power consumption is
