Claim:
1. A liquid crystal display device comprising: a liquid crystal display unit that displays an image; a plurality of electrodes arrayed in the liquid crystal display unit in parallel with one direction along a display surface of the liquid crystal display unit; a power line that extends in the one direction and that is commonly coupled to the electrodes; 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, wherein the electrodes are separated into pairs of the electrodes, including a first pair of the electrodes positioned at either end of the array of the electrodes, and a second pair of the electrodes positioned in the array of the electrodes other than both ends of the array of the electrodes, and a distance between the power line and first end parts of the first pair of the electrodes is smaller than a distance between the power line and second end parts of the second pair of the electrodes such that an electric resistance value between the power line and the first end parts is smaller than an electric resistance value between the power line and the second end parts, and a heating value of the first pair of the electrodes is larger than a heating value of the second pair of the electrodes when the voltage for causing the electrodes to generate heat is applied.
