Display device

A display device comprising:

• a display panel including a plurality of pixels each having a plurality of sub-pixels;
• and a
• light path adjustment film on the display panel,
• wherein the light path adjustment film includes a first base film, and a pattern layer on a surface of the first base film,
• wherein the pattern layer includes a plurality of first patterns having a first refractive index, and a plurality of second patterns between the plurality of first patterns and having a second refractive index less than the first refractive index,
• wherein each of the plurality of first patterns includes a top surface spaced apart from the display panel and parallel with the display panel, a bottom surface between the top surface and the display panel and overlapping the top surface, and a slanted surface connecting the top surface and the bottom surface,
• wherein the bottom surface of each of the plurality of first patterns is wider than the top surface of the first pattern that overlaps the bottom surface,
• wherein each of the plurality of first patterns overlaps a corresponding one sub-pixel from the plurality of pixels,
• wherein a width of a bottom surface of a first pattern from the plurality of first patterns is wider than a width of an opening region and non-opening regions of a sub-pixel of a given pixel that corresponds to the first pattern,
• wherein the opening region is between the non-opening regions of the sub-pixel of the given pixel, and
• wherein a width of a top surface of the first pattern is wider than the width of the opening region of the sub-pixel of the given pixel, and is equal to or less than the non-opening regions of the sub-pixel of the given pixel.
