Display

The invention provides a display. The display comprises a display panel and a photonic crystal panel. The photonic crystal panel is located on the display panel and comprises a first electrode, a second electrode and an optical film. The second electrode overlaps the first electrode. The optical film is located between the first electrode and the second electrode. The optical film includes a first portion and a second portion. The first portion includes a plurality of first photonic crystals, and the second portion includes a plurality of second photonic crystals. The periodically arranged microstructure of each first photonic crystal is different from the periodically arranged microstructure of each second photonic crystal. 本发明提出一种显示器。显示器包括显示面板以及光子晶体面板。光子晶体面板位于显示面板上，且包括第一电极、第二电极以及光学膜。第二电极重叠于第一电极。光学膜位于第一电极与第二电极之间。光学膜包括第一部与第二部。第一部包括多个第一光子晶体，且第二部包括多个第二光子晶体。各第一光子晶体的周期性排列微结构不同于各第二光子晶体的周期性排列微结构。
