The embodiment is that heater 4 is accommodated in the knot for being set to the inside of opening portion 6 of circuit substrate 5 in a manner of falling into
Structure.Therefore, circuit substrate 5 will not be caused far from liquid crystal display panel 1 because of the thickness of heater 4 as the prior art, so as to
Enough reduce the loop shape of electric wire 9.As a result, in liquid crystal display device, the amount of wire protective material 11 can be reduced, so ring
Reduction is shunk in the expansion of the caused wire protective material 11 of border variation, so as to reduce the stress for being applied to electric wire 9.Cause
And liquid crystal display device can prevent the broken string etc. of electric wire.
In addition, being able to suppress in liquid crystal display device and electrically connecting the second substrate 3 of liquid crystal display panel 1 with circuit substrate 5
The increase of the amount of the electroconductive resin 10 connect, therefore the expansion of electroconductive resin 10 caused by environmental change can be prevented, received
Removing, broken string caused by contracting etc..
In the case that liquid crystal display panel 1 and circuit substrate 5 are electrically connected by electric wire especially in liquid crystal display device, energy
Enough inhibit the increase of the height of electric wire.In addition, in the case that electric wire is covered by wire protective material in liquid crystal display device, energy
Enough inhibit the increase of the coating amount of wire protective material, therefore the broken string etc. of electric wire can be prevented.
The feelings that liquid crystal display panel 1 and circuit substrate 5 are electrically connected by electroconductive resin especially in liquid crystal display device
Under condition, it is able to suppress the increase of the amount of electroconductive resin, therefore the bad connection of electroconductive resin, liquid crystal display panel 1 can be prevented
The uneven generation of display.
The electrical connection areas of the first substrate 2 of liquid crystal display panel 1 and circuit substrate 5, liquid crystal display panel 1 the second substrate 3 with
The electrical connection areas of circuit substrate 5 and the electrical connection areas of heater 4 and circuit substrate 5 are not limited to Figure 1A~figure
Region shown in 1C can also be other regions.In addition, these join domains can also be multiple.
The transparent electrode of heating layer as heater 4 can be identically formed in the entire unilateral interarea of transparent substrate or
Person is formed as electrode pattern.But it's not limited to that for the heating layer of heater 4, the heating layer as heater 4, it is possible to use its
His material and shape etc..In addition, the heating layer of heater 4 may be alternatively provided as the first substrate 2 for not contacting liquid crystal display panel 1.
Fig. 3 A is the top view of the liquid crystal display device of another embodiment, and Fig. 3 B is the liquid crystal display of another embodiment
The rearview of device.The liquid crystal display device has similarly to be constituted with Figure 1A~Fig. 1 C, liquid crystal display device shown in Fig. 2.
But in the liquid crystal display device, in the circuit base opposite with the both ends of the transverse direction of heater 4 (the horizontal direction D1 in Fig. 3 A)
On position on plate 5, bridgees across the length degree of the longitudinal direction (the horizontal direction D2 in Fig. 3 A) of heater 4 and be formed with electronic pads 27
