  • Patent number: 10177176
    Abstract: To prevent light leakage and compensate for a step between a display region and a non-display region, a thin film transistor array substrate can include a base substrate having a display region and a non-display region, a plurality of pixel regions defined by gate lines and data lines crossing each other in the display region of the base substrate, a common line corresponding to between adjacent pixel regions, a thin film transistor and a color filter in each pixel region, a first dummy color filter between the adjacent pixel regions, a second dummy color filter in the non-display region on the base substrate, the second dummy color filter being provided at an upper surface thereof with at least one recess, and a protective film over the entire surface of the base substrate to cover the first and second dummy color filters and fill the recess.
    Type: Grant

  • Patent number: 9354453
    Abstract: The display device includes a display panel including upper and lower array substrates, and a patterned retarder to separate an image displayed on the display panel into left-eye and right-eye images, wherein the lower array substrate includes gate and data lines to define pixel areas, a pixel electrode formed at each pixel area, and a black stripe formed at a boundary between the pixel areas to display the left-eye image and the pixel areas to display the right-eye image, wherein the black stripe includes a first black stripe formed on the same layer and formed of the same material as an opaque layer of a thin film transistor, and a second black stripe overlapped with the first black stripe and formed on the same layer and formed of the same material as the pixel electrode.
