Abstract: A display device includes a display panel including a pixel that includes sub-pixels for emitting light in respective colors, and a driver configured to adjust a current amount flowing through the sub-pixels and to adjust an emission duty of the sub-pixels, drive one sub-pixel among the sub-pixels having a luminance with a first current amount and with a first emission duty when a color coordinate of an image expressed by the pixel is within a reference color space, and drive the one sub-pixel having the luminance with a second current amount that is greater than the first current amount and with a second emission duty that is less than the first emission duty when the color coordinate is outside of the reference color space.

Abstract: A display device includes a planarization layer disposed on a substrate, a first electrode disposed on the planarization layer and including silver (Ag), a contact preventing layer disposed on the first electrode, including a light absorbing material, and including a top surface and a side surface extending from an end of the top surface, and a pixel defining layer disposed on the contact preventing layer and including a bottom surface facing the top surface of the contact preventing layer, and a side surface extending from an end of the bottom surface. The first electrode includes a first region overlapping pixel defining layer. The contact preventing layer includes a second region overlapping the first region between the first electrode and the pixel defining layer. A first edge where the top and side surfaces of the contact preventing layer meet is located on the bottom surface of the pixel defining layer.
