Abstract
A display control device of the present invention include a correction circuit (11) that obtains integrated values by integrating, for a period of 0.5 frame or longer, each of the values of voltages corresponding to input levels of gray that are applied to two display pixels on the same gate lines, obtains voltage values by adding the difference between the integrated values to each of the values of the voltages corresponding to the input levels of gray, and uses the voltage values as output levels of gray of the current frame that are given to the two display pixels. This prevents the appearance of transcriptions in displaying 1-dot horizontal stripes during double-source driving.
