FIELD: optics.
SUBSTANCE: invention relates to a mobile terminal with an optical device located under a display module. Mobile terminal comprises an optical device, a display module and an optical antireflection film. Display module is located above the optical device, the optical antireflection film is located on the display module and corresponds to the optical device. Display module comprises display screen and protective layer, display screen is located above optical device and protective layer is located above display screen. Display module further comprises a transparent adhesive layer which is disposed between the display screen and the protective layer. Difference between the refractive index of the transparent adhesive layer and the refractive index of the protective layer is greater than 0.1, and the optical antireflection film is provided between the protective layer and the transparent adhesive layer.
EFFECT: invention increases efficiency of the optical device located under the display module.
