Abstract:
Embodiments of the present invention relate to a display screen, comprising a cathode metal layer, a packaging layer provided on the upper surface of the cathode metal layer, and an organic light-emitting layer provided on the lower surface of the cathode metal layer. The organic light-emitting layer comprises a non-light-emitting region and a plurality of light-emitting regions; the display screen further comprises a light shielding layer; the light shielding layer is provided on the upper surface of the packaging layer or between the cathode metal layer and the packaging layer, and the light-shielding layer is used for shielding the non-light-emitting region in the organic light-emitting layer. By means of the light shielding layer added by the embodiments of the present invention, ambient light reflection of the cathode metal layer is effectively reduced, a polarizer layer is omitted, and the display problem caused by ambient light reflection of the cathode metal layer is avoided with a relatively thin thickness.
