As illustrated in FIG. 5, the liquid crystal device 100 includes a display signal output circuit 111, a multiplexer 112, a signal generation circuit 113, a control circuit 114, and a driving circuit 115, each of which serves as a circuit relating to driving the liquid crystal device. The liquid crystal panel 110 of the liquid crystal device 100 is provided with a plurality of pixels P in the display region E1. As described above, the pixel P includes the pixel electrode 15 (see FIG. 2), the TFT 30 (see FIG. 2) serving as a switching element for the pixel electrode 15, and a holding capacitor (not illustrated) for holding potentials applied to the pixel electrode 15. In the peripheral region E2 (see FIG. 1) surrounding the display region E1, a first electrode 121, a second electrode 122, and a third electrode 123, each of which has a frame shape, are provided to surround the display region E1. The first electrode 121, the second electrode 122, and the third electrode 123 are collectively referred to as a peripheral electrode 120 configured for ion trapping. Alternatively, these are also referred to as three electrodes 121, 122, and 123 configured for ion trapping. The counter electrode 23 is disposed to overlap the peripheral electrode 120 in plan view. The ion trapping mechanism according to the present exemplary embodiment includes the peripheral electrode 120 and the counter electrode 23 that are disposed to oppose each other by interposing the liquid crystal layer 50.
