Abstract: An optical film may include a first pattern layer having a first refractive index and including a base portion and a plurality of protrusions on the base portion x, and a second pattern layer disposed on the first pattern layer and having a second refractive index different from the first refractive index. Each of the protrusions may include n sub-protrusions (n is an integer of 2 or greater), which are stacked in a thickness direction of the base portion. Each of the n sub-protrusions may have a quadrilateral shape. A side surface of the protrusion defined by the n sub-protrusions may include at least one step portion. The optical film improves display quality of a display device in front and lateral directions.

Abstract: A display device includes a first base substrate, first through n-th gate lines, first through (m+1)-th data lines, and a plurality of pixels. Each of the first through n-th gate lines extends in a first direction. Each of the first through (m+1)-th data lines extends in a second direction crossing the first direction. The plurality of pixels is arranged in a matrix form. Each of the plurality of pixels is coupled to a corresponding one of the gate lines and a corresponding one of the data lines. Each pixel in the first column among the plurality of pixels is independently driven from each pixel in the second column among the plurality of pixels. Pixels in the first column and pixels in the m-th column are provided in the non-display area. Pixels coupled to the first data line and pixels coupled to the (m+1)-th data line display a black image.
