  • Publication number: 20230180519
    Abstract: A display device having a display panel, a polarization film disposed on the display panel, and a plurality of retardation films disposed on the polarization film. Each of the plurality of retardation films has different in-plane phase differences Rin, and the in-plane phase difference Rin of each of the plurality of retardation films is 10000 nm or larger. According to an example embodiment, a color distortion, such as color irregularity, a color shift, and interference colors, is improved and the visibility of the rainbow stain is minimized or reduced.

  • Publication number: 20220415983
    Abstract: A display device includes pixels each including a first sub-pixel, a second sub-pixel and a third sub-pixel. Each of the pixels includes a bank disposed on a substrate, wherein the bank includes a first opening defining a light-emitting area of the first sub-pixel, a second opening defining a light-emitting area of the second sub-pixel, and a third opening defining a light-emitting area of the third sub-pixel, and a spacer being disposed on the bank and surrounding the third opening. Spacers in adjacent pixels have different shapes from each other.

  • Patent number: 10928682
    Abstract: A display device and a method of manufacturing the same are disclosed. The display device comprises a thin film transistor on a substrate, a protective film on the thin film transistor, and an alignment film on the protective film. The protective film includes one or more protective films, and a protective film adjacent to the alignment film among the one or more protective films has a silicon content higher than a nitrogen content. Thus, it is possible to provide a display device capable of reducing image sticking or flicker.
