Abstract: A color conversion display panel includes a substrate. A color conversion portion is disposed on the substrate. The color conversion portion includes a semiconductor nanocrystal. A transmission portion is disposed on the substrate. A blue light blocking filter is disposed between the substrate and the color conversion portion. The blue light blocking filter includes a first convex portion that protrudes toward the substrate. The transmission portion includes a first region including a scatterer and a second region including a second convex portion that protrudes toward the substrate.

Abstract: A pixel includes a light-emitting element, a driving switching element and a noise switching element. The driving switching element applies a driving current to the light-emitting element. The noise switching element outputs a noise signal having a noise frequency to an input electrode of the driving switching element in response to a noise control signal. The noise frequency is equal to or greater than a driving frequency of the pixel. The noise signal having a periodicity is applied to the input electrode of the driving switching element of the pixel.
