According to an aspect, a liquid crystal display device includes: a liquid crystal display unit that displays an image; a plurality of electrodes arranged in the liquid crystal display unit in parallel with one direction along a display surface of the liquid crystal display unit; a measuring unit that measures electric resistance values of the electrodes; a specifying unit that specifies a temperature of the liquid crystal display unit based on the electric resistance values of the electrodes; and an application unit that applies, to the electrodes, a voltage for causing the electrode to generate heat based on the temperature of the liquid crystal display unit.
