Abstract

A display device includes a substrate, at least three light emitting elements and a light adjusting layer. The light adjusting layer includes at least one light adjusting structure and is disposed on the light emitting elements. One light adjusting structure is corresponding to the light emitting elements. The display device provides a sum of viewing-angles of a first number of the light emitting elements when the first number of the light emitting elements is turned on, and the display device provides a sum of viewing-angles of a second number of the light emitting elements when the second number of the light emitting elements is turned on. The first number is less than the second number, and the sum of viewing-angles of the first number of the light emitting elements is less than the sum of viewing-angles of the second number of the light emitting elements.
