Patent ID: 8866996

Claim:
A liquid crystal display comprising: a liquid crystal display panel comprising a thin film transistor substrate and a liquid crystal layer disposed on the thin film transistor substrate; a heat generation unit that is configured to heat the liquid crystal layer; a resistance sensing unit that senses a change in a magnitude of resistance of the heat generation unit; a heat generation unit power controller that decreases a magnitude of power applied to the heat generation unit when the magnitude of resistance of the heat generation unit is equal to or greater than a reference magnitude of resistance; a power supply unit that supplies power of a designated magnitude to the heat generation unit power controller; and a backlight unit comprising: a light source disposed at a lower side of the liquid crystal display panel opposite to a display surface of the liquid crystal display panel, wherein the light source is provided at one side of a light guide plate which converts a line light source into a surface light source so as to allow light irradiated from the light source to be incident upon an entire surface of the liquid crystal display panel; and optical sheets that guide the light irradiated from the light source to the surface of the liquid crystal display panel opposite to the display surface, wherein the heat generation unit is provided between the liquid crystal display panel and the backlight unit.
