Abstract
A display panel includes a first substrate including a transistor; a pixel electrode electrically connected to the transistor; a common electrode opposing the pixel electrode; an emission layer between the pixel electrode and the common electrode, the emission layer emitting light; a second substrate opposing the first substrate; a light control electrode on the second substrate; and a filling layer between the light control electrode and the common electrode, a refractive index of the filling layer being changed based on a voltage difference between the light control electrode and the common electrode.
