Abstract: A color conversion substrate and a display device including the same. The color conversion substrate includes a color filter layer having a plurality of color filters, and a color conversion layer disposed on the color filter layer. The color conversion layer includes a plurality of dams, and a plurality of conversion parts disposed between the dams. A reflection layer is disposed on the dams, and a hydrophobic area is disposed on the reflection layer, overlapping an upper surface of the dams, and non-overlapping a side surface of the dams. The display device further includes a light source configured to output a first color light to the color conversion substrate.

Abstract: A display device including a display panel and a light source to irradiate to the display panel a first color light having a peak wavelength within a specific wavelength range. The display panel includes a first display substrate, a second display substrate facing the first display substrate and including a base substrate, a metal layer, which includes metal grid patterns disposed on the base substrate, and a color conversion layer, which is disposed on the base substrate to cover the metal grid patterns, and a liquid crystal layer provided between the first and second display substrates. The metal grid patterns are configured to block a fraction of an ambient incident light that is in a specific wavelength range, and a peak wavelength of the first color light is within the specific wavelength range.

Abstract: A display device includes a display panel and a light source for outputting a first color light to the display panel. The display panel includes a first display substrate, a second substrate facing the first substrate, and a liquid crystal layer disposed between the first display substrate and the second substrate. The second display substrate includes a base substrate, a color filter layer including a plurality of color filters spaced apart from each other on the base substrate, a color conversion layer including a plurality of dams, and a plurality of conversion parts overlapping the color filters, disposed on the base substrate, and disposed between the plurality of dams, a reflection layer disposed on the dams, and a hydrophobic area disposed on the reflection layer, overlapping an upper surface of the dams, and non-overlapping a side surface of the dams.
