Flat Panel Display Device

A flat panel display device, which can reduce manufacturing costs is disclosed. The flat panel display device includes a display panel for displaying images and a plurality of driving integrated circuits for driving the display panel. Each of the plurality of driving integrated circuits includes a timing controller for arranging input image data such that the image data is suitable for driving of the display panel and generating a plurality of data control signals and a data driver for converting the image data provided from the timing controller into data voltages in response to the plurality of data control signals. Intervals during which the timing controllers of the driving integrated circuits supply clock signals to the data drivers of the corresponding driving integrated circuits are different.
