A pen input liquid crystal display has row electrodes, column electrodes orthogonal to the row electrodes, and a liquid crystal layer interposed between the row and column electrodes. A pen input detecting signal is applied to one of the column electrodes, and display signals to the other column electrodes. The column electrode that receives the pen input detecting signal is sequentially shifted among the column electrodes, to simultaneously carry out a pen input scanning operation and an image displaying operation.
