1. A display device, comprising:
a color filter including,
a first electrode and a second electrode spaced apart from each other, anda variable filter layer between the first electrode and the second electrode,the variable filter layer including a plurality of liquid crystals dispersed in a first polymer, and a plurality of color display materials mixed in the liquid crystals, andthe variable filter layer being divided into a plurality of pixel units, wherein each of the pixel units includes a plurality of sub-pixels displaying different colors; an optical shutter portion in which transmittance of incident light is individually controlled in a region corresponding to each of the plurality of sub pixels, the optical shutter portion including an optical shutter layer on the color filter, and the optical shutter layer including a material in which transmittance of incident light varies under electrical control; and a reflection layer under the color filter, the reflection layer being configured to reflect light entering through the color filter in a direction towards the color filter, wherein at least one of the first and second electrodes has a mesh pattern, and wherein an electrode portion of the mesh pattern is disposed only in a region facing a dead zone between the plurality of sub-pixels.
