Abstract:
1. A liquid crystal display device including a plurality of scan signal lines, a plurality of data signal lines to which video signals are supplied as data signals, and a displaying section including pixels arranged in a matrix manner, the pixels respectively connected, via switching sections, with the scan signal lines and the data signal lines corresponding to intersecting points thereof, the liquid crystal display device comprising: a temperature sensor provided in at least one of the pixels in a displaying region of the displaying section; a lead line provided unnoticeably in the displaying section, for transmitting a detection signal from the temperature sensor to a peripheral section of the displaying section; a temperature measurement control section for measuring a temperature based on the detection signal transmitted from the temperature sensor; a data signal line driving section for outputting the data signal to the data signal lines in a manner based on the temperature measured in the temperature measurement control section; and spare lines respectively corresponding to the data signal lines and branched to be connected with the data signal lines in such a manner that a ladder-like shape is formed with the spare lines and the data signal lines, the spare lines being for ensuring transmission of the data signal even if breaking occurs in a data signal line, the spare lines also functioning as the lead line.
