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.

Method of fabricating a display panel and a display device with the display panel

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.

Display device and method for manufacturing the display device

A method of manufacturing an imprint stamp including forming an imprint resist only in a second area of a sample substrate including a first area and the second area, pressing the imprint resist with the imprint stamp and curing the imprint resist, in which the imprint stamp includes a fine protrusion pattern that corresponds to the first area and the second area of the sample substrate, and separating the imprint stamp from the sample substrate such that a portion of the fine protrusion pattern corresponding to the second area is separated from the imprint stamp by the cured imprint resist.

Method of manufacturing imprint stamp and display apparatus manufactured using the imprint stamp

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.
