PROBLEM TO BE SOLVED: To provide a liquid crystal display device of which the whole heater does not warp by heat even while efficiently heating a liquid crystal panel by the heater.SOLUTION: A circuit board 10 is provided with a slit 11 so as to surround a heater electrode 7 on the surface of the circuit board 10. A part of the slit 11 is provided with a connection part 12 connecting the center part with the periphery of the circuit board 10, the end of the heater electrode 7 is laid on the surface of the connection part 12, and connected to a terminal 6 on the periphery of the circuit board 10. Since heat generated by the heater electrode 7 is hard to be conducted to the periphery of the circuit board 10 by being hindered by an air space in the slit 11, for that, a liquid crystal panel 1 can be efficiently heated, and a warp of the whole circuit board 10 due to the heat can be suppressed. |
