Abstract: A display device includes a plurality of color filters that is disposed on a first base substrate and in pixel regions arranged in a matrix shape, a plurality of driving electrodes that is disposed on the color filters, a plurality of transistors that is provided on the first base substrate and in a non-pixel region between adjacent pixel regions in a second direction and is connected to the driving electrodes, a plurality of blocking column spacers that is provided below a second base substrate and in the non-pixel region between the adjacent pixel regions in the second direction and extending in a first direction, and a plurality of dummy color filters that is provided in a single-layered structure on the transistors. The dummy color filters that has a less number than that of the transistors support the blocking column spacers.

Abstract: A display panel includes an upper display substrate including pixel areas arranged in each of pixel columns and a light blocking area and a lower display substrate including display elements respectively overlapping the pixel areas. The upper display substrate includes a base substrate, a color filter layer, and a light control layer including transmission portions overlapping first pixel areas arranged in a first pixel column and first conversion portions overlapping second pixel areas arranged in a second pixel column, and a barrier layer including first barriers disposed between the first conversion portions and the transmission portions and first sub-barriers disposed between adjacent first conversion portions. A first shortest distance from the base substrate to a lower surface of each of the first barriers is equal to a second shortest distance from the base substrate to a lower surface of each of the first sub-barriers.
