  • Publication number: 20220173156
    Abstract: A display device includes a first via layer on a substrate and including trench parts recessed from an upper surface of the first via layer, a first electrode and a second electrode on the first via layer and spaced apart from each other, a second via layer on the first via layer and including first openings partially exposing the first electrode, and a second opening partially exposing the second electrode, light emitting elements in the first openings of the second via layer and extending in a direction, and a third electrode on the second via layer. Each of the light emitting elements includes a first end electrically connected to the first electrode and a second end electrically connected to the third electrode such that the extending direction of the light emitting elements is not parallel to an upper surface of the substrate.

  • Publication number: 20160116775
    Abstract: A display device according to an exemplary embodiment of the present invention having each pixel that comprises first and second subpixel areas, and an outer partition may be formed along a row direction between a plurality of liquid crystal layers, and the outer partition may separate a first liquid crystal injection hole and a second liquid crystal injection hole of two liquid crystal layers that are adjacent to each other along a column direction, thus liquid crystals are separated rather than being mixed with each other and fill their corresponding microcavities of the first and second subpixels areas.
