Abstract: A color conversion panel for a display device includes: a substrate including a first region, a second region, and a third region; a light-blocking partition disposed on the substrate and having a plurality of openings via which the first region, the second region and the third region are exposed; color conversion patterns disposed on the substrate in the openings in the first region and in the second region, respectively; and a light-transmitting layer containing scattering particles and including a first portion disposed in the opening in the third region and a second portion disposed to cover the color conversion patterns on the substrate. The scattering particles increase the efficiency of color conversion, such that color gamut may be increased.

Abstract: A display device and a method of manufacturing a display device, the display device having a plurality of pixels defined therein and including: a first substrate; a partition wall disposed on the first substrate to define openings corresponding to the plurality of pixels; and color conversion patterns disposed in the openings. The partition wall includes a light-transmitting structure having a groove and a first partition wall portion disposed in the groove and having a higher optical density than the light-transmitting structure.

Abstract: A display device includes: a first substrate including a display area to emit a light having a peak wavelength from light emitting areas and a non-display area surrounding the display area; and a second substrate including transparent areas overlapping the light emitting areas and to convert the peak wavelength of the light or to transmit the light through the transparent areas. The second substrate includes: a base layer including the transparent areas, an inner light blocking area arranged between the transparent areas, and an outer light blocking area arranged outside the transparent areas; a color filter on the base layer; and a light blocking layer above the color filter and including an outer light blocking layer overlapping the outer light blocking area and an inner light blocking layer overlapping the inner light blocking area.
