Electronic device

Abstract

An electronic device includes a base layer; a light source disposed on the base layer; and a plurality of optical films disposed on the base layer, wherein the electronic device respectively has a first brightness value, a second brightness value and a third brightness value, which satisfy: ❘ "\[LeftBracketingBar]" [ ( A / C ) - ( B / C ) ] × 100 ⁢ % ❘ "\[RightBracketingBar]" ≧ 10 ⁢ % , where A, B and C represents the first, second and third brightness values, respectively, the first brightness value is a second maximum brightness value of the electronic device, the second brightness value is a minimum brightness value of the electronic device, and the third brightness value is a maximum brightness value of the electronic device.
