Abstract: A display device may include a first layer, a passivation layer, and a pixel. The passivation layer may overlap the first layer and may include a first passivation portion and a second passivation portion. The pixel may include a first-color filter, a first-color-corresponding electrode, a second-color filter, and a second-color-corresponding electrode. The first-color-corresponding electrode may overlap the first-color filter and may be positioned between the first layer and the first passivation portion. The second-color-corresponding electrode may overlap the second-color filter. The second passivation portion may be positioned between the first layer and the second-color-corresponding electrode.
