Abstract: A display device includes a display panel layer, a light transmission layer disposed on the display panel layer, where a plurality of trenches is defined in the light transmission layer to be recessed in a first direction towards the display panel layer, and a light blocking material filling the plurality of trenches. A profile on a section of each of the plurality of trenches includes a first parallel section, a connection section, and a second parallel section, which are sequentially defined along the first direction. A first width of the profile on the section in a second direction perpendicular to the first direction in the first parallel section is smaller than a second width of the profile on the section in the second direction in the second parallel section.
