no. 2 Embodiment approach
[0168]
[0169] Figure 11 It is a schematic sectional view showing the structure of the liquid crystal device of the second embodiment. Figure 12 It is a graph showing the relationship between the mobility μ of ionic impurities and temperature. Below, refer to Figure 11 and Figure 12 The configuration of the liquid crystal device and the relationship between the mobility μ of the ionic impurities and the temperature will be described.
[0170] The liquid crystal device 200 of the second embodiment differs from the liquid crystal device 100 of the above-mentioned first embodiment in that it includes a temperature sensor 71 for measuring the temperature of the liquid crystal panel 110 , and the other parts are substantially the same. Therefore, in the second embodiment, parts different from those in the first embodiment will be described in detail, and descriptions of other overlapping parts will be appropriately omitted.
[0171] Such as Figure 11 As shown, the liqu...
no. 3 Embodiment approach
[0183]
