A PCB of an LCD is provided to prevent the fault of a screen generated by noise of power inputted from the outside. An LCD(200) includes a data line(D1,D2). A data driving unit(110) is connected to the data line. A signal processing unit(130) processes image data inputted from the outside to output the image data to the data driving unit. A power noise sensing unit(150) outputs a noise sensing signal corresponding to noise to the data driving unit when the noise is included in the power inputted from the outside. The data driving unit stops the processing of the image data inputted from the signal processing unit when the noise sensing signal is inputted, processes the processing image data before the noise sensing signal is inputted, and outputs the image data to the data line. |
