Abstract

An electronic device includes a light adjustment element; and a light source providing element disposed below the light adjustment element and including a light guide plate; a light source adjacent to the light guide plate; a first prism structure disposed on the light guide plate and facing the light guide plate; a second prism structure disposed on the first prism structure and facing the light adjustment element; and a third prism structure disposed on the second prism structure and facing the light adjustment element. An extension direction of the first prism structure is perpendicular to an extension direction of the light source. An included angle between an extension direction of the second prism structure and the extension direction of the light source is 45 or 135 degrees. An extension direction of the third prism structure is not perpendicular to the extension direction of the second prism structure.
