Zusammenfassung:An electronic device is provided. The electronic device includes a panel and an optical element. The optical element is disposed on the panel. The optical element includes a first surface away from the panel. The first surface has a microstructure, and the microstructure has an arithmetical mean deviation of the profile (Ra). The optical element has a thickness. In addition, the arithmetical mean deviation of the profile (Ra) and the thickness conform to the following formula: 0.00001≤arithmetical mean deviation of the profile/thickness≤0.0104.
