1. A display device comprising:
a first substrate comprising a first glass substrate, a first switching element arranged in a display area, a first pixel electrode electrically connected to the first switching element, a second pixel electrode arranged outside the display area, and a feed line;
a second substrate comprising a second glass substrate, and a common electrode facing the first pixel electrode and the second pixel electrode;
a sealant bonding the first substrate with the second substrate;
a liquid crystal layer surrounded by the sealant between the first substrate and the second substrate, and containing polymer dispersed liquid crystal;
a third glass substrate comprising a side surface and bonded to the second glass substrate with an adhesive layer; and
a light emitting module arranged along the side surface, wherein
the feed line is at a same potential as the common electrode,
the sealant comprises a first portion along the side surface between the light emitting module and the display area, and
the second pixel electrode is electrically connected to the feed line in a region between the first portion of the sealant and the display area.
