Abstract

An exemplary display screen includes a display module and an anti-reflective module at one side thereof. The anti-reflective module includes a plurality of refraction structures connected in sequence. Each refraction structure includes a connection section and a plurality of refraction sections. The refraction sections are connected to both sides of the connection section and form an included angle with the connection section to form indented anti-reflection structures.
