DISPLAY DEVICE COLOR FILTER PATTERNS AND A BLACK MATRIX

A display device includes a first substrate including a pixel region and a peripheral region at least partially surrounding the pixel region and a plurality of pixels disposed in the pixel region. The plurality of pixels includes first, second and third sub-pixels each having a light emitting region. The display device further includes light emitting elements respectively disposed in the light emitting regions of the first to third sub-pixels and a color conversion layer having color filter patterns corresponding to respective light emitting elements. At least one of the color filter patterns has a size smaller than that of the light emitting elements in a first direction of the first substrate, and the rest of the color filter patterns has a size larger than that of the light emitting elements in the first direction of the first substrate.
