Abstract:
1. A liquid crystal display device comprising: a first substrate having a plurality of gate and data lines on a first side thereof to define a plurality of pixels and a plurality of gate and data pads connected to the respective gate and data lines, the pixel including an image displaying unit for displaying an image and an image non-displaying unit; a thin film transistor formed adjacent to a crossing of the gate line and the data line; a second substrate having a black matrix and a color filter on the first side thereof, the black matrix being disposed in a first region corresponding to the image non-displaying unit of the first substrate; a first polarization plate and a second polarization plate attached respectively to the first substrate and the second substrate; liquid crystal molecules positioned between the first and second substrates; a heat generating electrode for generating heat in response to a direct current being supplied to the heat generating electrode, the heat generating electrode being directly deposited in a second region corresponding to the black matrix on a second side of the second substrate opposing to the first side; a heating pad formed at the first side of the first substrate, the heating pad being electrically connected to the heat generating electrode at the second side of the second substrate for supplying the direct current to the heat generating electrode, wherein the heating pad is made of a same material as the gate and data pads; a conductive tape for connecting electrically the heating pad with the heat generating electrode and with a case enclosing the first and second substrates; and a backlight unit for irradiating light onto the first and second substrates, wherein the heat generating electrode is disposed between the second substrate and the second polarization plate.
