a display panel including a first area, and a second area spaced apart from the first area in a plan view, the display panel further including a front major surface on a front side and a rear major surface opposite the front major surface on an opposing rear side of the display device, wherein the display panel comprises:

a first base layer including a first pixel, the first pixel producing a first image on the front major surface that is viewable from the front side of the display device;

a second base layer facing the first base layer and including a second pixel, the second pixel producing a second image on the rear major surface that is viewable from the rear side of the display device;

a first signal line electrically connected to the first pixel of the first area;

a second signal line electrically connected to the second pixel of the second area; and

a connection line electrically connecting the first signal line and the second signal line, the connection line being disposed between the first base layer and the second base layer, wherein

the connection line allows the second image to be produced simultaneously with that of the first image on the opposing sides of the display device with left and right portions of each of the images not being reversed.
