Abstract: A display device includes a display substrate, a liquid crystal layer disposed on the display substrate, a common electrode disposed on the liquid crystal layer, a first protection layer disposed on the common electrode, a polarizer unit disposed on the first protection layer, and a color conversion layer disposed on the polarizer unit. The polarizer unit includes a polarizing portion that polarizes light, and a blocking portion that blocks transmittance of light. The blocking portion is connected to the common electrode through a contact hole. The contact hole is an opening in the first protection layer.
