Abstract

The present invention provides a micro structure, a display apparatus and a display panel thereof. The display panel includes a display module and a cover glass disposed on the display module. A microstructure array is disposed on a surface of the cover glass facing away from the display module. The microstructure array includes a plurality of microstructure units arranged along a first direction, and each the microstructure unit includes a plurality of microstructures aligned in a second direction. Odd rows and even rows of the microstructure unit in the microstructure array both are aligned in the first direction. The arbitrary adjacent microstructure units in the microstructure array are offset in the second direction, by a predetermined shift distance. Through the microstructure array, reflection rate of cover glass surface is reduced, thus the display effect of a display panel is improved.
