Abstract: A display panel includes a pixel including sub pixels. The pixel includes a sub pixel area in which the sub pixels are disposed and a common area. The pixel includes a light emitting diode including an anode electrode and a cathode electrode, and the anode electrode is electrically connected to a first power line to which a high potential voltage is supplied. Each of the sub pixels includes a driving element in which a source is connected to a N1 node, a gate is connected to a N2 node, and a drain is connected to a N3 node, a capacitor connected to the N2 node and a N4 node; a N1 switching circuit connected to the N1 node; a N2 switching circuit connected to the N2 node; a N3 switching circuit connected to the N3 node; and a N4 switching circuit connected to the N4 node.

Abstract: Discussed are a backlight unit and an autostereoscopic 3D (three-dimensional) display device including the same, in which a 3D image can be displayed without using a 3D light controller that includes a liquid crystal layer. The backlight unit may include a 3D light guide plate having first light output patterns, first light sources irradiating light to at least one side of the 3D light guide plate, a 2D (two-dimensional) light guide plate arranged below the 3D light guide plate, and second light sources irradiating light to at least one side of the 2D light guide plate. The first light output patterns are a plurality of line prism patterns spaced apart from each other.
