1. A liquid crystal display device, comprising:

  • a liquid crystal display panel having first and second substrates bonded to each other and separated from each other by liquid crystal material, wherein at least one of the first and second substrates includes a display area and a non-display area, the liquid crystal panel including a plurality of gate lines crossing a plurality of data lines to define pixels within the display area;

    a thermally conductive layer on any one of the first and second substrates, wherein the thermally conductive layer is formed within the display area, wherein the thermally conductive layer prevents a temperature-dependent formation of bubbles within the liquid crystal material;

    a thermal signal conductor on any one of the first and second substrates and connected to the thermally conductive layer;

    a first insulating film on the thermally conductive layer; and

    a protective film,wherein the thermal signal conductor includes;

    a first thermal signal electrode connected to the thermally conductive layer, wherein the first insulating film is between the first thermal signal electrode and the thermally conductive layer; and

    a second thermal signal electrode connected to the first thermal signal electrode and supplied with a thermal signal from a thermal signal generator, wherein the protective film is between the second and first thermal signal electrodes, wherein the second thermal signal electrode is formed on the non-display area,wherein the thermally conductive layer is excluded from regions of the display area occupied by portions of the gate and data lines.
