摘要： A display device that can reduce color shift and prevent the quality of an image from degrading due to moiré. The display device includes a display panel and an optical film, which includes a background layer disposed in front of the display panel, and a lens section formed on the background layer. Patterns of the lens section is spaced apart from each other to diffuse incident light. The spacing τ and pitch T of the patterns are determined by the following m value in the following formulae. I max - I min I max + I min ≈  2  sin  ( π · k · p / P ) ( π · k · p / P )  sin  ( π · m · p / P ) ( π · m · p / P )  ≤ 0.01 k = τ / T p / P m = P / T p/P is an aperture ratio of sub-pixels of the display panel, τ/T is an aperture ratio of the lens section, I is an intensity of light exiting the optical film after being diffused through the sub-pixels, P and p are a pitch and a width of the sub-pixels, T is a pitch of the patterns, and τ=T−W.
