Abstract: A display device includes a display panel, and a front panel overlapping with the display panel and being switched into a reflection state in which incident light is reflected and a transmission state in which incident light is transmitted. The front panel includes a first substrate, a second substrate facing the first substrate, a liquid crystal layer sealed between the first substrate and the second substrate, a first translucent electrode provided on a side of the first substrate on which the liquid crystal layer is located, a second translucent electrode provided on a side of the second substrate on which the liquid crystal layer is located, a discharge resistor that is electrically coupled to the second translucent electrode and is provided on the second substrate, and a first conductive pillar that electrically couples the first translucent electrode and the discharge resistor.
